Agency Contact: Priscilla Rohrer, Department of Environmental Quality, 4411 Early Road, P.O. Box 3000, Harrisonburg, VA 22801, telephone (540) 574-7852, FAX (804) 698-4178, or email priscilla.rohrer@deq.virginia.gov.

Basis: Section 10.1-1402 of the Code of Virginia authorizes the Virginia Waste Management Board to promulgate and enforce regulations. Section 10.1-1408.1 of the Code of Virginia requires a permit to be obtained to conduct nonhazardous solid waste disposal, treatment or storage activities. The Virginia Waste Management Board has adopted this regulation under the authority granted by state law.

The corresponding federal authority for the criteria for municipal solid waste landfills is found at 40 CFR Part 257 and 258.

Purpose: The Virginia Solid Waste Management Regulations (9VAC20-81) establish standards and procedures for the siting, design, construction, operation, maintenance, closure, and post-closure care of solid waste management facilities in the Commonwealth. It also establishes standards and procedures pertaining to the management of solid wastes. The proposed amendments are essential to protect the health, safety, and welfare of citizens because the amendments include changes related to landfill gas, groundwater monitoring, and daily operational requirements of landfills. The amendments are needed to provide addition protection the citizens in the vicinity of landfills from the operation of these facilities. The main goals of this amendment are to improve standards for the siting, operation and monitoring of landfills and revise the open burning exemptions to be more protective of human health and the environment.

Substance: Some of the major areas in which the regulations are being revised include the following:

Landfill siting: Changes are being made to the landfill siting criteria to update provisions related to setbacks and siting of solid waste facilities, as well as solid waste facility leachate pollution. Terminology used in the regulation pertaining to the siting setbacks is being updated to use the term "waste management boundary" to eliminate confusion by clarifying that the siting requirements for landfills apply to the locations where waste and leachate will be managed, not the entire parcel of the property. Changes have been made to clarify that the siting requirements apply to new and expanded waste management boundaries. The setback distance from the waste management boundary to the facility boundary is being increased from 50 feet to 100 feet, in response to consensus from the regulatory advisory panel (RAP). The distance from the waste management boundary to any residence, school, daycare center, hospital, nursing home, or recreational park area in existence at the time of application is also being increased from 200 feet to 500 feet. These changes will create a larger buffer between the waste management boundary and development on properties adjacent to the landfill. The regulation is also being amended in response to RAP consensus to state that a new or expanded waste management boundary will not be sited or constructed in any locally designated resource protection area as defined in 9VAC25-830-80.

Landfill operations: A new requirement is being included in the regulation for active landfills to conduct a periodic topographic survey. The surveys will provide more accurate and updated information to the facility and the department on the current capacity and grades of the fill area, the remaining life of the landfill, and assist with planning for future landfill capacity. Survey reports will supplement and validate information provided in solid waste information and assessment (SWIA) reports. This requirement will also help to ensure that the final elevations of the landfill are as permitted and will prevent the overfilling of landfills from occurring. Landfills receiving fewer quantities of waste (those with a permitted daily disposal limit of 300 tons per day or less) are only required to conduct the survey on a biennial basis (once every 24 months) whereas all other landfills must survey and report on an annual basis (once every 12 months). Some landfills are already required by their permit to conduct these surveys. A requirement for weekly cover to be applied over exposed waste at active industrial landfills is being added to the regulation. The amended regulation allows the department to evaluate alternate methods proposed by the facility to address the same performance standards.

Landfill gas monitoring: An additional requirement is being added for landfills to notify adjacent properties within 500 feet of gas compliance level exceedances (i.e., methane gas detected at or above the lower explosive limit) in the perimeter gas monitoring network. Facilities will be required to offer to monitor inside nearby offsite structures for elevated levels of methane after an exceedance is detected in the perimeter gas monitoring network.

Landfill groundwater monitoring: Revisions to the groundwater monitoring section for all landfills are being proposed to prepare for the addition of any maximum contaminant levels (MCLs) established for perfluoroalkyl and polyfluoroalkyl substances (PFAS) and other emerging contaminants by the Virginia Department of Health (VDH) that adds a new Column C, to Table 3.1 that lists emerging constituents that VDH is directed to establish MCLs for in the future in response to § 32.1-169 of the Code of Virginia. The regulation is also proposing to allow other test methods other than the Environmental Protection Agency's SW-846 methods for constituents listed in Column C of Table 3.1.

Open burning exemptions: This amendment removes language that previously allowed citizens to dispose of their household solid waste through open burning of waste on their property if regularly scheduled collection services were not available at the adjacent road. Under the amended regulation, only vegetative waste, clean wood, and clean paper products will be allowed to be open burned on private property when no regular collection services are available. Other open burning exemptions are also being modified to be consistent with open burning requirements for volatile organic compound (VOC) emissions control areas found in regulations adopted by the State Air Pollution Control Board.

Other changes: Minor clarifications and revisions have been made to the regulation, and some regulatory requirements have been reorganized as part of this amendment. Operational requirements applicable to non-landfill facilities have been clarified and consolidated where possible to assist the regulated community with understanding the requirements of the regulation. Changes are being made to the regulation to further promote composting activities. Additional exemptions from permitting have been added to the regulation for certain composting activities on farms as well as composting activities performed in conjunction with a public or private event or festival. The agency is also proposing to remove the requirement for compost facilities to conduct parasite testing as historical data has demonstrated that parasites have not posed issues with final compost quality. The regulation is also being revised to require closure cost estimates to include the costs related to the removal of stockpiled beneficial use materials at a facility. This amendment will require facilities' closure cost estimates to include costs for removal of beneficial use materials when calculating the financial assurance a facility is required to provide for closure of the facility.

Issues: Many of the changes being proposed to the regulation provide additional protection to human health and the environment; therefore, the changes are advantageous to private citizens. Advantages to the public, as residential areas increasingly expand toward preexisting landfills, include improved safety and reduced odor in the vicinity of landfills. Increases to setback distances will help to provide a larger buffer between landfill activities and adjacent properties. Private citizens will no longer be allowed to open burn their general household waste, except for vegetative waste, clean wood, and clean paper products, and they will need to arrange for their waste to be properly managed at a permitted solid waste management facility. This change should reduce nuisance complaints from neighbors concerning the impact open burning has on the air quality on neighboring properties. Changes being proposed to compost-related requirements, such as additional compost activities exempt from permitting and elimination of certain testing requirements for permitted facilities, will promote composting activities in the Commonwealth, reduce regulatory burden without posing risks to human health and the environment, and are advantageous to public and private entities, and well as the regulated community. There are no disadvantages to the agency or the Commonwealth.

The addition of regulatory requirements will impact the regulated community. This includes local governments and private companies that operate landfills. The additional regulatory requirements pertaining to the following areas are being added to the regulations to protect human health and the environment (i) increased setback distances from waste management boundaries; (ii) periodic topographic surveys of active landfills; (iii) revised cover requirements for active industrial landfills to meet required performance standards; (iv) notification and monitoring for neighbors in close proximity of landfill gas exceedances; and (v) groundwater monitoring of emerging contaminants, dependent upon actions taken by VDH. These issues are all related to the proper siting, operation and monitoring of the landfill and protecting the safety of those in proximity of the landfill. Owners and operators of landfills will incur costs to comply with these requirements.

Department of Planning and Budget's Economic Impact Analysis:

The Department of Planning and Budget (DPB) has analyzed the economic impact of this proposed regulation in accordance with § 2.2-4007.04 of the Code of Virginia (Code) and Executive Order 14 (as amended, July 16, 2018). The analysis presented represents DPB's best estimate of these economic impacts.¹

Summary of the Proposed Amendments to Regulation. Following action by the Governor, a periodic review, and the work of a regulatory advisory panel, the Virginia Waste Management Board (Board) proposes amendments to landfill siting, operations, and gas and groundwater monitoring, as well as a ban on the open burning of household trash.

Background. This regulatory proposal was developed by the Department of Environmental Quality (DEQ) staff based on the comments received during the periodic review and Notice of Intended Regulatory Action (NOIRA) comment periods, recommendations included in the August 2019 final report submitted by the Secretary of Natural and Historic Resources (Secretary) to the Governor in response to the Governor's Executive Order 6 (2018), meetings with members of the Regulatory Advisory Panel (RAP), and feedback from program staff.

Executive Order 6 (2018).² On April 3, 2018, Governor Northam issued Executive Order Six (EO 6), "Supporting the Critical Role of the Virginia Department of Environmental Quality in Protection of Virginia's Air, Water, and Public Health." This EO required the DEQ director to review the agency's permitting, monitoring, and enforcement activities across the air, water, and solid waste programs. It also required the DEQ director to work with stakeholders to improve communication with the public and the regulated community and provide more opportunities for proactive education, especially among underserved and lower income populations. The EO further mandated that the Director of DEQ report monthly to the Secretary on the progress of these reviews. The Secretary was also tasked with sending a report on recommended actions to the Governor.

Report Issued by Secretary of Natural Resources.³ In response to EO 6, the Secretary submitted a final report to the Governor in August 2019. The report recommends that solid waste management regulations be revised to: (1) ensure that facilities provide adequate financial assurance that they can fund cleanup and closure, (2) update provisions related to setbacks and siting of solid waste facilities, as well as solid waste facility leachate pollution, (3) eliminate or significantly reduce "with restrictions on timing, conditions, and residuals management "the open burning of household solid waste, and (4) require groundwater monitoring and safe disposal of Coal Combustion By-Product (CCB/coal ash) at non-utility facilities not covered by the federal CCB rule. Other sections of the report urge an increase in efficiency and responsiveness in permitting and an improvement in public engagement.

Periodic Review. ⁴ On June 10, 2019, a periodic review of this regulation was announced in the Virginia Register of Regulations. During the 21-day public comment period that followed, comments were received from ten individuals, four of whom posted comments on Town Hall; the others apparently contacted the agency directly. These comments suggested changes to the siting, design, operation, and monitoring of municipal solid waste landfills; requirements for host agreements; and public notification requirements. Commenters also provided information about other states' regulations in this area and requested that Virginia adopt similar requirements. Still other commenters requested additional regulation of, and requirements for, landfills larger than a specified size. The agency took these comments into consideration as it developed regulatory text in this action.

Regulatory Advisory Panel (RAP). A regulatory advisory group was formed to assist in developing this action and consisted of six members, including a representative of the waste management industry, a public citizen, a local government representative, two consultants (an engineer and a representative of the Solid Waste Association of North America), and a representative of environmental groups. According to the agency, a consensus was not achieved on a new or expanded landfill's setback distance to a residence, school, daycare center, hospital, nursing home, or recreational park area (described below), but there was agreement that the current distance should be increased. No consensus was reached on how often waste should be covered at an active industrial landfill (also described below), but there is now a provision that ameliorates that requirement by allowing an active industrial landfill to propose an alternative that would achieve the same result.

Estimated Benefits and Costs

Landfill Siting. One of the main changes proposed is an increase in the setback distance from a waste management boundary to the facility boundary, which would be increased from 50 feet to 100 feet. In addition, the distance from the waste management boundary to any residence, school, daycare center, hospital, nursing home, or recreational park area in existence at the time of application would be increased from 200 feet to 500 feet. These changes would create a larger buffer between the waste management boundary and development on properties adjacent to the landfill. DEQ notes that the additional buffer from the waste management boundary is consistent with the requests received from the public for an increased buffer space to be placed around landfills and is consistent with the increased setback distances found in surrounding states. The increase to the setback distances would potentially reduce noise and odor concerns, and provide more protection to adjacent properties from potential subsurface methane gas migration.

The proposed setback requirements are prospective in that the current landfills would be grandfathered from the revised setback distances. Increased setback distances would essentially create a larger buffer that would not be available for other uses, including the landfill's capacity. New and expanded landfill owners could meet the new siting criteria by increasing the land area to achieve the same capacity or by reducing the capacity if additional land area is not available or feasible. Thus, the expected cost to new and expanded landfill owners is either the purchase of additional land or a reduction in capacity. Conversely, values of real property that would be within the additional buffer areas created by this action may also be affected. For example, a landfill owner may choose to purchase additional real estate adjacent to a prospective site to keep the capacity as planned prior to this action. Or, some land may be rendered no longer suitable for siting as a landfill.

Landfill Operations. A new requirement for active landfills to conduct an annual topographic survey would be added to the regulation. Topographic surveys ensure the landfill is filled according to its permitted design capacity, prevent overfilling of the landfill and potential impacts to landfill stability, and verify when final elevations and slopes have been attained so that closure construction can be planned and implemented. Periodic topographic surveys also result in more accurate and up-to-date information on remaining capacity and life of the landfill. Landfills receiving fewer quantities of waste (those with a permitted daily disposal limit of 300 tons per day or less) would be required to conduct the survey on a biennial basis (once every 24 months), whereas all other landfills must survey and report on an annual basis (once every 12 months).

According to DEQ, some landfills are already required by their permit to conduct these surveys and some do so voluntarily. DEQ estimates that approximately 55 active landfills would be impacted by the requirement to conduct a periodic topographic survey because the remaining landfill permits already include this requirement. Based on the daily disposal limits of currently permitted landfills, approximately 35 active landfills would be impacted by the annual survey requirement, and approximately 20 active landfills would be impacted by the biennial survey requirement. Based on feedback from one large landfill that is already subject to this requirement by permit, the cost of the proposed survey is estimated to be $16,000 for that facility but could be as low as $5,000 for smaller facilities.

A requirement for weekly cover of six inches of compacted soil to be applied over exposed waste at active industrial landfills would be added. Currently, the regulation states that these facilities are to provide "periodic cover" without a specific time frame. According to DEQ, current inspection data indicates the periodic cover being applied is not adequate to prevent issues with fires, odors, blowing litter, stormwater infiltration, excess leachate generation, surface and subsurface erosion of waste, waste slides, compromised stability, and releases of waste and leachate at industrial landfills. In consideration of the RAP discussion and feedback, the proposed amendment allows DEQ to evaluate alternate methods proposed by the facility to address the same performance standards.

Twenty active industrial landfills, of which 19 are privately owned and operated (one is owned and operated by a local government authority), would be required to provide weekly cover. The soil used for weekly cover could be removed later and reused. The costs of application of weekly soil cover would vary depending on the landfill's adjusted ongoing working face size; the extent to which soil is removed and reused between lifts; and availability of soil onsite versus purchase and/or transport from offsite. The requirement for weekly cover would likely lead to industrial landfills minimizing the size of their working face to minimize the amount of weekly cover required to be applied, and would in turn minimize the amount of exposed waste at the facility. It is worth noting, however, that flexibility has been added to the regulation to allow landfills to investigate and propose less costly methods to meet the same performance standards based on site-specific conditions.

Landfill Gas Exceedance Notification. A new requirement would be added for landfills to notify adjacent properties within 500 feet when gas compliance levels have been exceeded (i.e., methane gas detected at or above the lower explosive limit) in the perimeter gas monitoring network. Landfill gas may migrate subsurface and accumulate in nearby off-site structures. The goal is to inform neighboring properties concerning the potential for the subsurface migration of methane and the safety risks related to explosive gases. Only landfills that detect compliance level exceedances of methane within 500 feet of an occupied structure would be impacted by this proposal.

The cost of sending notices to adjacent property owners would be consistent with regular mail costs, but is expected to provide landfill owners with an additional incentive to maintain compliance with exceedance limits. Increased awareness of a nearby problematic landfill operation may adversely affect the perceived values of nearby properties and may prompt complaints and litigation.

Additional costs to landfill owners may accrue as facilities would be required to offer monitoring inside nearby offsite structures for elevated levels of methane after an exceedance is detected in the perimeter gas monitoring network. The costs of additional monitoring would vary from site to site depending on whether exceedances are detected and whether occupied structures are in close proximity. DEQ does not expect the costs of additional offsite monitoring to be significant because the majority of landfills do not have occupied structures within 500 feet of the perimeter gas monitoring network, and any additional monitoring could be conducted in conjunction with the current monitoring that already occurs at the facility.

Monitoring of Additional Constituents in Groundwater. The proposed groundwater monitoring requirement is contingent upon the Maximum Contaminant Levels (MCLs) to be established for polyfluoroalkyl substances (PFAS) and other emerging contaminants by the Virginia Department of Health (VDH) pursuant to Chapter 1097, 2020 Acts of Assembly.⁵ Chapter 1097 modifies § 32.1-169 of the Code of Virginia (effective on January 1, 2022) and directs the State Board of Health to "adopt regulations establishing [MCLs] in all water supplies and waterworks in the Commonwealth for (i) [PFAS] as the board deems necessary; (ii) chromium-6; and (iii) 1,4-dioxane."

In anticipation of these new MCLs, a proposed amendment would add a new column, Column C, to Table 3.1 in the regulation. The proposed Column C lists emerging constituents for which MCLs will be established by VDH in response to the statutory mandate. The content of Column C can be modified in the future if necessary, based on the actions taken by VDH to adopt MCLs for emerging constituents. MCLs must be adopted by VDH before this regulation will be amended to require monitoring for these constituents; however, this information has been included in this amendment to provide a framework for these additional monitoring constituents and to provide the regulated community with insight concerning how these new MCLs would be incorporated in monitoring requirements for solid waste disposal facilities. Once final MCLs are adopted by VDH, Column C will be updated, if necessary, for consistency with MCLs adopted by VDH, and monitoring for constituents listed in Column C would be required for all landfills.

PFAS are manufactured chemicals that are found in many items that are allowed to be disposed in landfills, such as cookware and clothing. These chemicals do not degrade in the environment and thus leach into soil, air, and water. This may contribute to the presence of PFAS in the blood of 97% of Americans.⁶ Additionally, health risks from groundwater constituents are constantly being evaluated and updated. Including the monitoring of PFAS and other emerging constituents in groundwater is an additional measure to detect and address any impacts to groundwater from the landfill so that risks to human health and the environment can be better understood. All active landfills and all closed landfills conducting post-closure care may be impacted by the requirement for groundwater monitoring of additional constituents if VDH establishes MCLs for PFAS or other emerging contaminants listed in Column C of Table 3.1.

This would be an additional cost for entities that choose to own or operate a landfill. Members of the RAP provided cost information on analyzing groundwater samples. One estimate was for the testing for 49 PFAS constituents at a cost of $349 using a non-SW-846 test method (EPA test method 537.1). Other RAP members provided more general estimates of testing for PFAS of $350-$500 per sample, while others estimated costs of $500 to 700 per sample and did not indicate the analytical test method used. The regulation has been drafted to allow the use of non-SW-846 test methods for constituents listed in Column C of table 3.1 to provide flexibility concerning the test methods to be used.

The proposed list of new sampling constituents would be subject to the existing groundwater sampling frequency set for each individual site in its corresponding solid waste permit. Semi-annual is the baseline sampling frequency. However, site specific criteria or the locality may mandate quarterly sampling.

Ban on Open Burning of Household Trash. This proposal would remove language that previously allowed citizens to dispose of their household solid waste through open burning of waste on their property if regularly scheduled collection services are not available at the adjacent road. Under the amended regulation, only vegetative waste, clean wood and clean paper products would be allowed to be openly burned on private property when no regular collection services are available. This change is proposed in response to the Secretary's report to the Governor noted above, which recommended that the regulations be revised to eliminate or significantly reduce the open burning of household solid waste. DEQ states that combustion of materials commonly found in household waste (e.g. plastics) is well documented to release carcinogenic compounds, and the smoke and odors from the burning of household waste may be a nuisance to adjacent property owners. Other open burning exemptions are also being modified to be consistent with open burning requirements for Volatile Organic Compound Emissions Control Areas found in regulations adopted by the State Air Pollution Control Board.

DEQ expects a reduction in complaints from neighbors will result from this ban on open burning of household waste. Due to the unknown number of affected households and different fee structures implemented by localities to assess fees for waste disposal, however, DEQ is not able to assess the size of the economic impact of this change.

Promotion of Composting Activities. Changes are being proposed to the regulation to further promote composting activities. Additional exemptions from permitting have been added to the regulation for certain composting activities on farms as well as composting activities performed in conjunction with a public/private event or festival. The Board is also proposing to remove the requirement for compost facilities to conduct parasite testing because historical data has demonstrated that parasites have not posed issues with final compost quality.

Closure Cost Estimates. The regulation is also being revised to require that closure cost estimates include the costs related to the removal of stockpiled beneficial use materials (e.g. tire chips) at a facility in response to the Secretary's report noted above, which recommended that the regulations be revised to ensure that facilities provide adequate financial assurance that they can fund cleanup and closure. This amendment would require facilities' closure cost estimates to include costs for removal of beneficial use materials (which are not included currently) when calculating the financial assurance a facility is required to provide for closure of the facility. This change protects the Commonwealth from having to pay for the removal and disposal of beneficial use material if a facility fails to properly close.

Other Changes. The remaining proposed changes are clarifications of the following parts of the regulation: financial responsibility requirements, public participation, groundwater monitoring, exemptions and exclusions, closure and post closure requirements, permitting process, and recordkeeping requirements. These clarifying changes are not expected to create a significant economic impact other than improving the accuracy of the regulatory text.

Businesses and Other Entities Affected. DEQ reports that as of August 2021, 181 permitted landfills would be affected by the proposed amendments, including 128 sanitary landfills (80 closed), 24 construction/demolition/debris landfills (10 closed), and 29 industrial landfills (nine closed).

The Code of Virginia requires DPB to assess whether an adverse impact may result from the proposed regulation.⁷ An adverse impact is indicated if there is any increase in net cost or reduction in net revenue for any entity, even if the benefits exceed the costs for all entities combined. As noted above, the proposed amendments add new requirements and would increase costs for landfills. Thus, an adverse impact is indicated.

This regulation also applies to permitted non-landfill facilities which include 15 compost facilities, 55 transfer stations, 53 materials recovery facilities, four waste to energy facilities, three incinerators, and eight surface impoundments. DEQ anticipates that the impacts to non-landfill facilities would be minimal as the proposed changes affecting these facilities clarify the intent of existing requirements and are consistent with industry standard practices.

No facilities appear to be disproportionately affected.

Of the permitted landfills, 126 are publicly owned or operated (125 by local governments and one by the Commonwealth), and 55 are privately owned or operated.

State agencies that own or operate waste management facilities would be subject to the same requirements as other publicly and privately owned or operated facilities. There are two permitted facilities owned or operated by state agencies a sanitary landfill in post-closure care and a compost facility. The landfill would incur ongoing costs for conducting PFAS monitoring and for notification of gas level exceedances as discussed above.

Citizens for whom no regularly scheduled collection services are available would no longer be allowed to burn their household waste (except for vegetative waste, clean wood, and clean paper products) and would be required to manage their waste at a solid waste permitted facility or convenience center. However, it is not known how many citizens are currently burning their municipal solid waste and would be impacted by this regulatory change.

Small Businesses⁸ Affected.⁹ In general, approximately 9.0% of all landfills (16 out of 181) are estimated by DEQ to be small businesses. Approximately 15% of 55 facilities impacted by the survey requirement are estimated to be small businesses. Approximately 10% of 20 active industrial landfills impacted by the weekly cover requirements are estimated to be small businesses. Thus, the proposed amendments also adversely affect small businesses.

Flexibility has been added to the regulation to allow industrial landfills impacted by the weekly cover requirement to investigate and propose less costly methods to meet the same performance standards based on site-specific conditions There are no clear additional alternative methods that both reduce adverse impact on small businesses and meet the intended policy goals.

Localities¹⁰ Affected.¹¹ Localities that own or operate waste management facilities would be subject to the same requirements as other publicly and privately owned or operated facilities. If operating an active landfill, a locality would be required to conduct annual topographic surveys, to monitor PFAS, to notify and take corrective action for gas level exceedances. There are 125 permitted landfills owned or operated by localities. Consequently, an adverse economic impact on these localities is indicated.

Projected Impact on Employment. The proposed requirements regarding the topographic survey, weekly cover, off-site gas monitoring, groundwater monitoring, and ban on open burning of household waste would likely add to demand for professional, skilled, and unskilled labor in related areas, and may commensurately increase employment.

Effects on the Use and Value of Private Property. The proposed new siting requirements are anticipated to have a direct impact on affected real estate properties as specifically discussed above. The asset values of 55 private landfill facilities would likely be negatively affected to the extent they incur additional compliance costs. The proposed amendments do not appear to have a direct effect on residential real estate development costs.

________________________________________

¹Section 2.2-4007.04 of the Code of Virginia requires that such economic impact analyses determine the public benefits and costs of the proposed amendments. Further the analysis should include but not be limited to: (1) the projected number of businesses or other entities to whom the proposed regulatory action would apply, (2) the identity of any localities and types of businesses or other entities particularly affected, (3) the projected number of persons and employment positions to be affected, (4) the projected costs to affected businesses or entities to implement or comply with the regulation, and (5) the impact on the use and value of private property.

Agency's Response to Economic Impact Analysis: The department has reviewed the economic impact analysis prepared by the Department of Planning and Budget and has no comment.

Summary:

The proposed regulatory action amends the Solid Waste Management Regulations (9VAC20-81), which establish standards and procedures for the siting, design, construction, operation, maintenance, closure, and post-closure care of solid waste management facilities in the Commonwealth. Substantive revisions include (i) updated provisions to setback, siting, operation, and monitoring requirements for landfills; (ii) updated provisions to open burn exemptions; (iii) increased promotion of composting; (iv) adequate closure cost estimates; and (v) clarification of many areas of the regulation.

General Information

9VAC20-81-25. Purpose of chapter.

A. The purpose of this chapter is to establish standards and procedures pertaining to the management of solid wastes by providing the requirements for siting, design, construction, operation, maintenance, closure, and postclosure post-closure care of solid waste management facilities in the Commonwealth in order to protect the public health, public safety the environment, and our natural resources.

B. This chapter provides for the prohibition of open dumping of solid waste to protect public health and safety and the environment.

C. This chapter sets forth the requirements for undertaking corrective actions at solid waste management facilities.

9VAC20-81-35. Applicability of chapter.

A. This chapter applies to all persons who treat, store, dispose, or otherwise manage solid wastes as defined in 9VAC20-81-95.

B. All facilities that were permitted prior to March 15, 1993, and upon which solid waste has been disposed of prior to October 9, 1993, may continue to receive solid waste until they have reached their vertical design capacity or until the closure date established pursuant to § 10.1-1413.2 of the Code of Virginia, in Table 2.1 provided:

1. The facility is in compliance with the requirements for liners and leachate control in effect at the time of permit issuance.

2. On or before October 9, 1993, the owner or operator of the solid waste management facility submitted to the director:

a. An acknowledgment that the owner or operator is familiar with state and federal law and regulations pertaining to solid waste management facilities operating after October 9, 1993, including postclosure care, corrective action, and financial responsibility requirements;

b. A statement signed by a professional engineer that he has reviewed the regulations established by the department for solid waste management facilities, including the open dump criteria contained therein, that he has inspected the facility and examined the monitoring data compiled for the facility in accordance with applicable regulations and that, on the basis of his inspection and review, he has concluded:

(1) That the facility is not an open dump;

(2) That the facility does not pose a substantial present or potential hazard to human health and the environment; and

(3) That the leachate or residues from the facility do not pose a threat of contamination or pollution of the air, surface water, or groundwater in a manner constituting an open dump or resulting in a substantial present or potential hazard to human health or the environment; and

c. A statement signed by the owner or operator:

(1) That the facility complies with applicable financial assurance regulations; and

(2) Estimating when the facility will reach its vertical design capacity.

3. Enlargement or closure of these facilities shall conform with the following subconditions:

a. The facility may not be enlarged prematurely to avoid compliance with this chapter when such enlargement is not consistent with past operating practices, the permit, or modified operating practices to ensure good management.

b. The facility shall not dispose of solid waste in any portion of a landfill disposal area that has received final cover or has not received waste for a period of one year, in accordance with 9VAC20-81-160 C. The facility shall notify the department, in writing, within 30 days, when an area has received final cover or has not received waste for a one-year period, in accordance with 9VAC20-81-160 C. However, a facility may apply for a permit, and if approved, can construct and operate a new cell that overlays ("piggybacks") over a closed area in accordance with the permit requirements of this chapter.

c. The facilities subject to the restrictions in this subsection are listed in Table 2.1. The closure dates were established in Final Prioritization and Closure Schedule for HB 1205 Disposal Areas (DEQ, September 2001). The publication of these tables is for the convenience of the regulated community and does not change established dates. Any facility, including, but not limited to those listed in Table 2.1, must cease operation if that facility meets any of the open dump criteria listed in 9VAC20-81-45 A 1.

d. Those facilities assigned a closure date in accordance with § 10.1-1413.2 of the Code of Virginia shall designate on a map, plat, diagram, or other engineered drawing, areas in which waste will be disposed of in accordance with Table 2.1 until the latest cessation of waste acceptance date as listed in Table 2.1 is achieved. This map or plat shall be placed in the operating record and a copy shall be submitted upon request to the department in order to track the progress of closure of these facilities. If the facility already has provided this information under 9VAC20-81-160, then the facility may refer to that information.

If soil sources are consistent (i.e. similar USCS soil type, liquid and plastic limits, grain size distribution, moisture density relationship, and permeability characteristics) one test pad will be adequate provided that the third-party quality control firm agrees. In the event that soils are not uniform within a borrow source an additional test pad shall be constructed for each soil type.

The test pad shall establish the range of criteria (compaction, moisture content, USCS classification, and grain size) that can be expected to achieve a low permeability soil liner meeting the requirements of the permit. To achieve these results the test pad's permeability shall be correlated with grain size analysis, liquid and plastic limits, moisture content, relative compaction, remolded permeability, undisturbed Shelby tube sample permeability, and the in-situ permeability determined by field tests performed on the test pad.

(2) Following the completion of the test pad the remaining low permeability liner system shall be certified by testing the constructed liner to determine its conformance to the acceptable criteria established during the test pad construction. Such tests shall include compaction, moisture content, grain size, and the liquid and plastic limits of the soil. Any area that does not conform to the established criteria shall be further tested by obtaining an undisturbed Shelby tube sample of the constructed liner and performing a laboratory permeability on it. In addition to testing any liner areas that do not conform to the established test pad acceptance criteria, a minimum of one additional laboratory permeability test shall be performed on each acre of constructed liner.

As a result of any statistically significant increase identified while monitoring groundwater under subdivision B 2 or 3, or C 2 or 3 of this section, or at anytime any time within the Corrective Action corrective action process under 9VAC20-81-260, the owner or operator has the option of submitting an Alternate Source Demonstration report, certified by a qualified groundwater scientist, demonstrating:

(1) A source other than the landfill caused the statistical exceedance;

(2) The exceedance resulted from error in sampling, analysis, or evaluation; or

(3) The exceedance resulted from a natural variation in groundwater quality.

b. Timeframes. A successful demonstration must be made within 90 days of noting a statistically significant increase. The director may approve a longer timeframe for submittal and approval of the Alternate Source Demonstration with appropriate justification.

c. Evaluation and response. Based on the information submitted in accordance with subdivision 5 a of this subsection, the director will:

(1) In the case of the successful demonstration of an error in sampling, analysis, or evaluation, allow the owner or operator to continue monitoring groundwater in accordance with the monitoring program in place at the time of the statistical exceedance.

(2) In the case of a successful demonstration of an alternate source for the release or natural variability in the aquifer matrix:

(a) Require changes in the groundwater monitoring system as needed to accurately reflect the groundwater conditions and allow the owner or operator to continue monitoring groundwater in accordance with the monitoring program in place at the time of the statistical exceedance;

(b) Require any changes to the monitoring system be completed prior to the next regularly scheduled groundwater monitoring event or within 90 days (whichever is greater) a date selected by the director; and

(c) Require any changes to the monitoring system be approved via the modification process under 9VAC20-81-600 within 90 days of the approval of the alternate source demonstration.

(3) In the case of an unsuccessful Alternate Source Demonstration, require the owner or operator to initiate the actions that would otherwise be required as a result of the statistically significant increase noted under subdivision B 2 or 3, or C 2 or 3 of this section as appropriate.

6. Establishment of groundwater protection standards.

a. Requirement. Upon recognition of a statistically significant increase over background and while monitoring in the Assessment or Phase II monitoring programs defined under subdivision B 3 or C 3 of this section, the owner or operator shall propose a groundwater protection standard for all detected Table 3.1 Column Columns B and C constituents. The proposed standards shall be submitted to the department by a qualified groundwater scientist and be accompanied by relevant historical groundwater sampling data to justify the proposed concentration levels.

b. Establishment process. The groundwater protection standards shall be established in the following manner:

(1) For constituents for which a maximum contaminant level (MCL) has been promulgated under § 1412 of the Safe Drinking Water Act (40 CFR Part 141) or by Virginia Department of Health regulation, the MCL for that constituent shall be automatically established as the groundwater protection standard upon submission of the proposed standards.

(2) If the owner or operator determines that a site-specific background concentration is greater than the MCL associated with that constituent under subdivision 6 b (1) of this subsection, the background value may be substituted for use as the groundwater protection standard in lieu of the MCL for that constituent upon receiving written department approval.

(3) For constituents for which no MCL has been promulgated, site-specific background concentration value(s) values may be used upon receiving written department approval.

(4) For constituents for which no MCL has been promulgated, a risk-based alternate concentration levels may be used if approved by the director as long as:

(a) The owner or operator submits a request to the department asking for approval to use risk-based alternate concentration levels for a specific list of constituents and identifies that these constituents lack an MCL. In the request the owner or operator shall specify whether site-specific, independently calculated, risk-based alternate concentration levels will be applied, or if the facility will accept the default department-provided limits.

(b) The alternate concentration levels that may be provided as default values by the department and those independently calculated by the owner or operator are demonstrated to meet the following criteria or factors before they can be used as groundwater protection standards:

(i) Groundwater quality - The potential for adverse quality effects considering the physical and chemical characteristics of the waste in the landfill, its potential for migration in the aquifer; the hydrogeological characteristics of the facility and surrounding land; the rate and direction of groundwater flow; the proximity and withdrawal rates of groundwater users; the current and future uses of groundwater in the area; the existing quality of groundwater, including other sources of contamination and their cumulative impact on the groundwater quality.

(ii) Human exposure - Potential for health risks caused by exposure to waste constituents released from the landfill using federal guidelines for assessing the health risks of environmental pollutants; scientifically valid studies conducted in accordance with the Toxic Substances Control Act Good Laboratory Practice Standards (40 CFR Part 792); or equivalent standards. For carcinogens, the alternate concentration levels must be set based on a lifetime cancer risk level due to continuous lifetime exposure within the 1x10^-4 to 1x10^-6 range. For systemic toxicants, alternate concentration levels must be demonstrated to be levels to which the human population (including sensitive subgroups) could be exposed to on a daily basis without the likelihood of appreciable risk of deleterious effects during a lifetime.

(iii) Surface water - The potential adverse effect on hydraulically connected surface water quality based on the volume, physical and chemical characteristics of the waste in the landfill; the hydrogeological characteristics of the facility and surrounding land; the rate and direction of groundwater flow; the patterns of rainfall in the region; the proximity of the landfill to surface waters; the current and future uses of surface waters in the area and any water quality standards established for those surface waters; the existing quality of surface water, including other sources of contamination and the cumulative impact on surface water quality.

(iv) Other adverse effects - Potential damage to wildlife, crops, vegetation, and physical structures caused by exposure to waste constituents; the persistence and permanence of the potential adverse effects; and the potential for health risks caused by human exposure to waste constituents using factors shown in subdivision b (4) (b) (ii) of this subsection.

(5) In making any determination regarding the use of alternate concentration levels under this section, the director will:

(a) Consider any identification of underground sources of drinking water as identified by EPA under 40 CFR 144.7,

(b) Consider additional or modified monitoring requirements or control measures,

(c) Include a schedule for the periodic review of the alternate concentration levels, or

(d) Approve the alternate concentration levels as proposed or issue modified alternate concentration levels.

c. Implementation. Groundwater protection standards shall be considered established for the facility upon completion of the actions described under either subdivision A 6 b (1), (2), (3) or if necessary (4) and shall be placed in the facility Operating Record and shall be used during subsequent comparisons of groundwater sampling data consistent with the requirements of subdivision B 3 f or C 3 e of this section.

d. MCL and background revisions. After establishment of groundwater protection standards under subdivision B 6 b, if the standards are modified as a result of revisions to any MCL or department-approved background, the facility shall update its listing of groundwater protection standards and shall place the new list in the Operating Record and shall use the new values during subsequent comparisons of sampling data consistent with the requirements of subdivision B 3 f or C 3 e of this section.

e. Alternate concentration levels revisions. After establishment of groundwater protection standards under subdivision B 6 b of this section, if the department-approved alternate concentration levels change based on information released by EPA, to the extent practical, the department will issue revisions to the alternate concentration levels for facility use no more often than an annual basis. The facility shall use the department approved alternate concentration levels listing in effect at the time the sampling event takes place when comparing the results against the groundwater protection standards under subdivision B 3 f or C 3 e of this section.

B. Monitoring for sanitary landfills.

1. Applicability.

a. Existing facilities. Except for those sanitary landfills identified in subdivision C 1 of this section, existing sanitary landfill facilities and closed facilities that have accepted waste on or after October 9, 1993, and in the case of 'small' "small" landfills on or after April 9, 1994, shall be in compliance with the detection monitoring requirements specified in subdivision 2 of this subsection unless existing sampling data requires a move to assessment monitoring described under subdivision 3 of this subsection.

b. New facilities. Facilities placed in operation to receive waste after October 9, 1993, shall be in compliance with the detection monitoring requirements specified in subdivision 2 of this section before waste can be placed in the landfill unless existing sampling data requires a move to assessment monitoring described under subdivision 3 of this subsection.

c. Closed facilities. Unless an extension to the deadline above has been granted by the director, closed facilities that have ceased to accept any waste on or before October 9, 1993, and in the case of a "small" landfill, before April 9, 1994, may comply with the "State Monitoring Program" monitoring requirements specified in subdivision C 2 or 3 of this section.

d. Other facilities. Owners or operators of disposal facilities not subject to the federal groundwater monitoring requirements prescribed under 40 CFR Parts 257 and 258 must perform the groundwater monitoring described in subdivision C 2 or 3 of this section.

e. Proximity to wetlands. Owners or operators of sanitary landfills that accepted waste after June 30, 1999, must:

(1) Perform quarterly groundwater monitoring unless the director determines that less frequent monitoring is necessary consistent with the requirements of the special provisions regarding wetlands in § 10.1-1408.5 of the Code of Virginia.

(2) The quarterly monitoring frequency shall remain in effect until the department is notified waste is no longer being accepted at the sanitary landfill.

(3) This requirement will not limit the authority of the Waste Management Board or the director to require more frequent groundwater monitoring if required to protect human health and the environment.

(4) For purposes of this subdivision "proximity to wetlands" shall be defined as landfills that were constructed on a wetland, have a potential hydrologic connection to such a wetland in the event of an escape of liquids from the facility, or are within a mile of such a wetland.

2. Detection monitoring program.

a. Sampling requirements. All sanitary landfills shall implement detection monitoring except as otherwise provided in subdivision 1 of this subsection. The monitoring frequency for all constituents listed in Table 3.1 Column Columns A and C shall be as follows:

(1) Initial sampling period.

(a) For facilities that monitor groundwater on a semi-annual basis, a minimum of four eight independent samples from each well (background and downgradient) shall be collected and analyzed for the Table 3.1 Column Columns A and C constituents prior to the facility becoming active or during the first semi-annual sampling period. A semi-annual period is defined under 9VAC20-81-10.

(b) For facilities that monitor groundwater on a quarterly basis as a result of subdivision 1 e of this subsection, a minimum of four samples from each well (background and downgradient) shall be collected and analyzed for the Table 3.1 Column Columns A and C constituents. The samples shall be collected within the first quarterly period, using a schedule that ensures, to the greatest extent possible, an accurate calculation of background concentrations.

(2) Subsequent sampling events. At least one sample from each well (background and downgradient) shall be collected and analyzed during subsequent semi-annual or quarterly events during the active life and postclosure post-closure period. Data from subsequent background sampling events may be added to the previously calculated background data so that the facility maintains the most accurate representation of background groundwater quality with which to carry out statistical analysis required under subdivision A 4 h of this section.

(3) Alternate sampling events. The director may specify an appropriate alternate frequency for repeated sampling and analysis during the active life (including closure) and the postclosure post-closure care period. The alternate frequency during the active life (including closure) and the postclosure post-closure period shall be no less than annual. The alternate frequency shall be based on consideration of the following factors:

(a) Lithology of the aquifer and unsaturated zone;

(b) Hydraulic conductivity of the aquifer and unsaturated zone;

(c) Groundwater flow rates;

(d) Minimum distance between upgradient edge of the disposal unit boundary and downgradient monitoring well screen (minimum distance of travel); and

(e) Resource value of the aquifer.

(4) Data from the background wells during each subsequent sampling event shall be added to the previously calculated background data for the recalculation of site background once every four years, unless approval for a longer timeframe is obtained from the department, to maintain the most accurate representation of background groundwater quality for statistical purposes required under subdivision A 4 h of this section.

b. Evaluation and response. If the owner or operator determines under subdivision A 4 h of this section, that there is:

(1) A statistically significant increase over background as determined by a method meeting the requirements of subsection D of this section, for one or more of the constituents listed in Table 3.1 Column Columns A and C at any of the monitoring wells at the disposal unit boundary during any detection monitoring sampling event, the owner or operator shall:

(a) Within 14 days of this finding, notify the department of this fact, indicating which constituents have shown statistically significant increases over background levels; and

(b) Within 90 days, (i) establish an assessment monitoring program meeting the requirements of subdivision 3 of this subsection, or (ii) submit an Alternate Source Demonstration as specified in subdivision A 5 of this section. If, after 90 days, a successful demonstration has not been made, the owner or operator shall initiate an assessment monitoring program as otherwise required in subdivision 3 of this subsection. The 90-day Alternate Source Demonstration period may be extended by the director for good cause.

(c) If, after 90 days, a successful demonstration has not been made, initiate an assessment monitoring program as otherwise required in subdivision 3 of this subsection. The 90-day Alternate Source Demonstration period may be extended by the director for good cause.

(2) No statistically significant increase over background as determined by a method meeting the requirements of subsection D of this section, for any of the constituents listed in Table 3.1 Column Columns A and C at any of the monitoring wells at the disposal unit boundary during any detection monitoring sampling event; the owner or operator may remain in detection monitoring and include a discussion of the sampling results and statistical analysis in the semi-annual or quarterly report required under subdivision E 2 c of this section.

3. Assessment monitoring program. The owner or operator shall implement the assessment monitoring program whenever a statistically significant increase over background has been detected during monitoring conducted under the detection monitoring program.

a. Sampling requirements. Within 90 days of recognizing a statistically significant increase over background for one or more of the constituents listed in Table 3.1 Column Columns A, and C the owner or operator shall, unless in receipt of an approval to an Alternate Source Demonstration under subdivision A 5 of this section or a director-approved extension, conduct the initial assessment monitoring sampling event for the constituents found in Table 3.1 Column Columns B and C. A minimum of one sample from each well installed under subdivision A 3 a of this section shall be collected and analyzed during the initial and all subsequent annual Table 3.1 Column Columns B and C sampling events.

b. Director provisions:

(1) The Subset establishment. Based on the results of the initial site-wide Table 3.1 Columns B and C assessment monitoring event, the owner or operator may request that the director approve an appropriate subset of monitoring wells that may remain in detection monitoring defined under subdivision 2 of this subsection, based on the results of the initial, or subsequent. Subsequent to this initial annual Table 3.1 Column Columns B and C sampling events. event, any new downgradient compliance well installed shall be allowed the opportunity to join the subset based on the results of the initial Table 3.1 Columns B and C monitoring event completed at the new well. Monitoring wells under either option described in this subdivision b (1) may be considered for the subset if:

(a) They show no detections of Table 3.1 Column Columns B and C constituents other than those already previously detected in detection monitoring defined under subdivision 2 of this subsection; and

(b) They display no statistically significant increases over background for any constituents on the Table 3.1 Column Columns A and C list. If an statistically significant increase is subsequently recognized in a well already approved for the subset, the well shall no longer be considered part of the detection monitoring subset.

(2) Modifications to the constituent list. The owner or operator may request the director delete any of the Table 3.1 Column Columns B and C monitoring constituents from the assessment monitoring program if the owner or operator demonstrates that the deleted constituents are not reasonably expected to be in or derived from the waste.

(3) Sampling frequency. The director may specify an appropriate alternate frequency for repeated sampling and analysis for the full set of Table 3.1 Column Columns B and C constituents required by subdivision 3 a of this subsection during the active life and postclosure post-closure care period based on the consideration of the following factors:

(a) Lithology of the aquifer and unsaturated zone;

(b) Hydraulic conductivity of the aquifer and unsaturated zone;

(c) Groundwater flow rates;

(d) Minimum distance between upgradient edge of the disposal unit boundary and downgradient monitoring well screen (minimum distance of travel);

(b) Report this data in the semi-annual or quarterly report defined under subdivision E 2 c of this section;

(3) Within 180 days of the initial sampling event, establish background concentrations for any Table 3.1 Column Columns B and C constituents detected pursuant to subdivision B 3 a of this subsection. A minimum of four eight independent samples from each well (background and downgradient) shall be collected and analyzed to establish background for the detected constituents unless a lessor number of samples has been approved by the department based on a site-specific request certified by a qualified groundwater scientist and submitted by the owner or operator.

d. Establishment of groundwater protection standards. Within 30 days of establishing background under subdivision 3 c (3) of this subsection, submit proposed groundwater protection standards for all constituents detected under Assessment monitoring. The groundwater protection standards shall be approved by the director in accordance with the provisions of subdivision A 6 of this section.

e. Groundwater monitoring plan. No later than 60 days after approval of the groundwater protection standards in accordance with subdivision A 6 of this section, the owner or operator shall submit an updated Groundwater Monitoring Plan that details the site monitoring well network and sampling and analysis procedures undertaken during groundwater monitoring events. The owner or operator shall additionally:

(1) No later than 30 days after the submission of the Groundwater Monitoring Plan, request a permit modification to incorporate the plan and related groundwater monitoring modules into the landfill's permit in accordance with 9VAC20-81-600. The department may waive the requirement for a permit modification if the Groundwater Monitoring Plan included in the landfill's permit reflects current site conditions in accordance with the regulations.

(2) If the 30-day timeframe specified in subdivision 3 e (1) of this subsection is exceeded, the director will modify the permit in accordance with 9VAC20-81-600 E.

f. Evaluation and response.

(1) If the concentrations of all Table 3.1 Column Columns B and C constituents at all downgradient compliance wells are shown to be at or below background values, using the statistical procedures in subsection D of this section, for two consecutive Table 3.1 Column Columns B and C sampling events, the owner or operator shall notify the director of this finding in the semi-annual or quarterly monitoring report and may return to detection monitoring defined under subdivision 2 of this subsection.

(2) If the concentrations of any Table 3.1 Column Columns B and C constituents are found at all downgradient compliance wells to be above background values, but below the groundwater protection standards established under subdivision A 6 of this section using the statistical procedures in subsection D of this section, the owner or operator shall continue in assessment monitoring in accordance with this section and present the findings to the department in the semi-annual or quarterly report.

(3) If one or more Table 3.1 Column Columns B and C constituents are detected at any downgradient compliance well onsite at statistically significant levels above the groundwater protection standard established under subdivision A 6 of this section using the statistical procedures in subsection D of this section, the owner or operator shall:

(a) Within 14 days of this finding, notify the department identifying the exceeding monitoring well and the Table 3.1 Column Columns B and C constituents that have exceeded the groundwater protection standard.

(ii) Submit an Alternate Source Demonstration as specified in subdivision A 5 of this section. If a successful demonstration is made within 90 days, the owner or operator may continue monitoring in accordance with the assessment monitoring program pursuant to subdivision 3 of this subsection. If the 90-day period passes without demonstration approval, the owner or operator shall comply with the actions under 9VAC20-81-260 C within the timeframes specified unless the director has granted an extension to those timeframes.

(b) Describe the sampling results in the semi-annual or quarterly report.

C. Monitoring for CDD, industrial, and State Monitoring Program sanitary landfills.

1. Applicability.

a. Sanitary landfills. Owners or operators of sanitary disposal facilities that have ceased to accept solid waste prior to the federally imposed deadline of October 9, 1993, or in the case of a "small landfill" before April 9, 1994, are eligible, with the director's approval, to conduct the state groundwater monitoring program described in this section in lieu of the groundwater monitoring program required under subdivision B 2 or 3 of this section.

(2) If the 30-day timeframe specified in subdivision 3 d (1) of this subsection is exceeded, the director will modify the permit in accordance with 9VAC20-81-600 E.

e. f. Evaluation and response. After each subsequent Phase II monitoring event following establishment of groundwater protection standards, the concentration of Table 3.1 Column Columns B and C constituents found in the groundwater at each monitoring well installed pursuant to subdivision A 3 a of this section will be evaluated against the groundwater protection standards. The evaluation will be presented to the department in a semi-annual Phase II report. The evaluation will be as follows:

(1) If all Table 3.1 constituents are shown to be at or below background values at all downgradient compliance wells, using the statistical procedures in subsection D of this section, for two consecutive Table 3.1 Column Columns B and C sampling events, the owner or operator shall notify the director of this finding in the semi-annual report and may return to first determination monitoring;

(2) If any Table 3.1 Column Columns B and C constituents at all downgradient compliance wells are found to be above background values, but are below the established groundwater protection standard using the statistical procedures in subsection D of this section, the owner or operator shall continue semi-annual Phase II monitoring and present the findings in a semi-annual report;

(3) If one or more Table 3.1 Column Columns B and C constituents are found at any compliance well above the established groundwater protection standard using the statistical procedures in subsection D of this section, the owner or operator shall:

(a) Notify the department within 14 days of this finding. The notification will include a statement that within 90 days the owner or operator will either: (i) undertake the characterization and assessment actions required under 9VAC20-81-260 C 1; or (ii) submit an alternate source demonstration as specified in subdivision A 5 of this section. If a successful demonstration is made within 90 days, the owner or operator may continue monitoring in accordance with Phase II monitoring program. If the 90-day period is exceeded, the owner or operator shall comply with the timeframes of 9VAC20-81-260 C unless the director has granted an extension to those timeframes; and (i) the wells in which the exceedance was identified and the constituent names; and (ii) a statement that within 90 days the owner or operator will either undertake the characterization and assessment actions required under 9VAC20-81-260 C 1 or submit an alternate source demonstration as specified in subdivision A 5 of this section.

(b) If a successful demonstration is made within 90 days, the owner or operator may continue monitoring in accordance with the Phase II monitoring program. If the 90-day period is exceeded, the owner or operator shall comply with the timeframes of 9VAC20-81-260 C unless the director has granted an extension to those timeframes; and

(c) Present the findings sampling results in the semi-annual report.

D. Statistical methods and constituent lists.

1. Acceptable test methods. The following statistical test methods may be used to evaluate groundwater monitoring data:

a. A parametric analysis of variance (ANOVA) followed by multiple comparisons procedures to identify statistically significant evidence of contamination. The method must include estimation and testing of the contrasts between each compliance well's mean and the background mean levels for each constituent.

b. An analysis of variance (ANOVA) based on ranks followed by multiple comparisons procedures to identify statistically significant evidence of contamination. The method must include estimation and testing of the contrasts between each compliance well's median and the background median levels for each constituent.

c. A tolerance or prediction interval procedure in which an interval for each constituent is established from the distribution of the background data, and the level of each constituent in each compliance well is compared to the upper tolerance or prediction limit.

d. A control chart approach that gives control limits for each constituent.

e. Another statistical test method that meets the performance standards specified below. Based on the justification submitted to the department, the director may approve the use of an alternative test. The justification must demonstrate that the alternative method meets the performance standards in subdivision 2 of this subsection.

2. Performance standards. Any statistical method chosen by the owner or operator shall comply with the following performance standards, as appropriate:

a. The statistical method used to evaluate groundwater monitoring data shall be appropriate for the distribution of monitoring parameters or constituents. If the distribution is shown by the owner or operator to be inappropriate for a normal theory test, then the data shall be transformed or a distribution-free theory test shall be used. If the distributions for the constituents differ, more than one statistical method may be needed.

b. If an individual well comparison procedure is used to compare an individual compliance well constituent concentration with background constituent concentrations or a groundwater protection standard, the test shall be done at a Type I error level no less than 0.01 for each testing period. If a multiple comparisons procedure is used, the Type I experiment-wise error rate for each testing period shall be no less than 0.05; however, the Type I error of no less than 0.01 for individual well comparisons must be maintained.

c. If a control chart approach is used to evaluate groundwater monitoring data, the specific type of control chart and its associated parameter values shall be protective of human health and the environment. The parameters shall be determined after considering the number of samples in the background data base, the data distribution, and the range of the concentration values for each constituent of concern.

d. If a tolerance interval or a predictional interval is used to evaluate groundwater monitoring data, the levels of confidence and, for tolerance intervals, the percentage of the population that the interval must contain, shall be protective of human health and the environment. These parameters shall be determined after considering the number of samples in the background data base, the data distribution, and the range of the concentration values for each constituent of concern.

e. The statistical method shall account for data below the limit of detection with one or more statistical procedures that are protective of human health and the environment. Any estimated quantitation limit (EQL) that is used in the statistical method shall be the lowest concentration level that can be reliably achieved within specified limits of precision and accuracy during routine laboratory operating conditions that are available to the landfill.

f. If necessary, the statistical method shall include procedures to control or correct for seasonal and spatial variability as well as temporal correlation in the data.

E. Recordkeeping and reporting.

1. Records pertaining to groundwater monitoring activities shall be retained at a specified location by the owner or operator throughout the active life and postclosure post-closure care period of the landfill, and shall include at a minimum:

a. All historical groundwater surface elevation data obtained from wells installed pursuant to subdivision A 3 a of this section;

b. All historical laboratory analytical results for groundwater sampling events required under the groundwater monitoring programs as described in this section;

c. All records of well installation, repair, or abandonment actions;

d. All department correspondence to the landfill; and

e. All approved variances, well subsets, wetlands, or other such director/department director or department approvals.

2. Reporting requirements.

a. Annual report.

(1) An Annual Groundwater Monitoring Report shall be submitted by the owner or operator to the department no later than 120 days from the completion of sampling and analysis conducted under subdivision A 4 h of this section for the second semi-annual event or fourth quarterly event during each calendar year and shall by accompanied by:

(a) A signature page; and

(c) Description of the surrounding land use noting whether any adjoining land owners utilize private wells as a potable water source;

(d) A discussion of the topographic, geologic, and hydrologic setting of the landfill including a discussion on the nature of the uppermost aquifer (i.e., confined versus unconfined) and proximity to surface waters;

(e) A discussion of the monitoring wells network noting any modifications that were made to the network during the year or any nonperformance issues and a statement noting that the monitoring well network meets (or did not meet) the requirements of subdivision A 3 of this section;

(f) A listing of the groundwater sampling events undertaken during the previous calendar year;

(g) A table listing the constituents identified during the year's sampling events, their concentrations at the respective monitoring well, and if applicable, the related groundwater protection standard in effect during the sampling event;

(g) (h) A historical table listing the detected constituents, and their concentrations identified in each well during the sampling period; and

(h) (i) Evaluations of and appropriate responses to the groundwater elevation data; groundwater flow rate as calculated using the prior year's elevation data; groundwater flow direction (as illustrated on a potentiometric surface map); and sampling and analytical data obtained during the past calendar year.

b. Semi-annual or quarterly report.

(1) After each sampling event has been completed for the 1st first semi-annual or first, second and third quarterly groundwater sampling events, a semi-annual or quarterly monitoring report shall be submitted under separate cover by the owner or operator to the department no later than 120 days from the completion of sampling and analysis conducted under subdivision A 4 h of this section, unless as allowed under a director-approved extension. The report shall at a minimum contain the following items:

(a) Signature page signed by a professional geologist or qualified groundwater scientist;

(b) Landfill name and permit number;

(c) Statement noting whether or not all monitoring points within the permitted network installed to meet the requirements of subdivision A 3 a of this section were sampled as required under subdivision B 2 or 3 or C 2 or 3 during the event;

(d) Calculated rate and direction of groundwater flow as calculated using information obtained during the sampling period as required under subdivision A 4 c of this section; (e) The groundwater flow direction as determined during the sampling period as required under subdivision A 4 c of this section. This information shall be presented as in either plain text within the report or graphically as a potentiometric surface map;

(f) (e) Statement noting whether or not there were statistically significant increases over background or groundwater protection standards during the sampling period, the supporting statistical calculations, and reference to the date the director was notified of the increase pursuant to timeframes in subdivision B 2 or 3 or C 2 or 3, if applicable;

(g) (f) Copy of the full Laboratory Analytical Report including dated signature page (laboratory manager or representative) to demonstrate compliance with the timeframes of subdivision A 4 h of this section. The department will accept the lab report in CD-ROM format.

(2) In order to reduce the reporting burden on the owner or operator and potential redundancy within the operating record, a discussion of the second semi-annual or fourth quarterly sampling event results may be presented in the Annual Report submission.

c. Other submissions. Statistically significant increase notifications, well certifications, the first determination report, alternate source demonstration, nature and extent study, assessment of corrective measures, presumptive remedy proposal, corrective action plan or monitoring plan, or other such report or notification types as may be required under 9VAC20-81-250 or 9VAC20-81-260, shall be submitted in a manner which achieves the timeframe requirements as listed in 9VAC20-81-250 or 9VAC20-81-260.

9VAC20-81-260. Corrective action program.

A. Corrective action is required whenever one or more groundwater protection standard is exceeded at statistically significant levels. An owner or operator of a landfill may elect to initiate corrective action at any time; however, prior to such initiation, the appropriate groundwater protection standards for all Table 3.1 constituents shall be established consistent with 9VAC20-81-250 A 6. At any time during the corrective action process, the owner or operator may elect to pursue, or the director can determine that, interim measures as defined under subsection F of this section are required in accordance with subdivision E 3 of this section.

B. The director may require periodic progress reports when a corrective action program is required but not yet implemented. At any time during the corrective action process:

1. The owner or operator may elect to pursue, or the director can determine that, interim measures as defined under subsection F of this section are required in accordance with subdivision E 3 of this section;

2. The director may require periodic progress reports when a corrective action program is required but not yet implemented.

C. Characterization and assessment requirements.

1. Upon notifying the department that one or more of the constituents listed in Table 3.1 Column B has been detected at a statistically significant level exceeding the groundwater protection standards, the owner or operator shall, unless department approval of an Alternate Source Demonstration has been received as noted under 9VAC20-81-250 B 3 f (3) (a) (ii) or 9VAC20-81-250 C 3 e (3) (a) (ii):

a. Characterization. Within 90 days, install additional monitoring wells as necessary sufficient to define the vertical and horizontal extent of the release of constituents at statistically significant levels exceeding the groundwater protection standards including the installation of at least one additional monitoring well at the facility boundary in the direction of contaminant migration.

b. Notification. Notify all persons who own the land or reside on the land that directly overlies any part of the release if that contaminants, including their names and concentrations, have migrated offsite as indicated by based on the results of sampling of the characterization wells installed under subdivision 1 a of this subsection. This notification must be made within 15 days of completion of the characterization sampling and analysis efforts.

c. Assessment. Within 90 days, initiate an assessment of corrective measures or a proposal for presumptive remedy.

d. Financial assurance. Within 120 days, provide additional financial assurance in the amount of $1 million to the department as required by 9VAC20-70-113 using the mechanisms required in 9VAC20-70-140 of the Financial Assurance Requirements for Solid Waste Disposal, Transfer, and Treatment Facilities.

e. Public meeting. Prior to submitting the document required under subdivision 1 f of this subsection, schedule and hold a public meeting to discuss the draft results of the corrective measures assessment or the proposal for presumptive remedy, prior to the final selection of remedy. The meeting shall be held to the extent practicable in the vicinity of the landfill. The process to be followed for scheduling and holding the public hearing is described under subdivision 4 of this subsection.

f. Submission requirements. Within 180 days, submit the completed assessment of corrective measures defined under subdivision 3 of this subsection, or the proposal for presumptive remedies defined under subdivision 2 of this subsection, including any responses to public comments received.

g. Director allowance. The submission timeframe noted in subdivision 1 f of this subsection may be extended by the director for good cause upon request of the owner or operator.

2. Presumptive remedy allowance.

a. Applicability. To expedite corrective action, in lieu of an analysis meeting the requirements of subdivision 3 of this subsection, the owner or operator of any facility monitoring groundwater in accordance with 9VAC20-81-250 C may propose a presumptive remedy for the landfill.

b. Options. The presumptive remedy for solid waste landfills shall be limited to one or more of the following:

(1) Containment of the landfill mass, including an impermeable cap;

(2) Control of the landfill leachate;

(3) Control of the migration of contaminated groundwater;

(4) Collection and treatment of landfill gas; and

(5) Reduction of saturation of the landfill mass.

Containment may be selected as a sole or partial remedy until a determination is made under subdivision F 1 of this section that another remedy shall be employed to meet the requirements of subdivision G 1 of this section concerning remediation completion. Upon recognition that presumptive remedies may not be able to achieve the groundwater protection standards, an assessment of corrective measures shall be initiated within 90 days.

c. Restrictions. Presumptive remedies are not applicable to:

(1) Landfills monitoring groundwater under the Federal Subtitle D equivalent program defined under 9VAC20-81-250 B when the use of the presumptive remedy will be the sole remedy applied to the groundwater release; or

(2) Landfills that may monitor groundwater under 9VAC20-81-250 C but that exhibit contamination beyond facility boundaries unless the proposed presumptive remedy option under subdivision 2 b of this subsection can be demonstrated to show it will address the reduction of contamination already present beyond the facility boundary, and the demonstration is approved by the department.

d. Submission requirements. Owner or operators who wish to propose use of the presumptive remedy allowance shall submit with the proposal, signed by a qualified groundwater professional, an:

(1) Assessment of risks resulting from the groundwater contamination identified at the disposal unit boundary and at as well as the permitted facility boundary;

(2) Evaluation of the current trends in groundwater quality data with respect to site background and the established groundwater protection standards; and

(3) Anticipated schedule for initiating and completing presumptive remedy-based remedial activities.

e. Implementation. Upon conducting a public meeting as required under subdivision 4 of this subsection, submitting a corrective action monitoring plan meeting subdivision D 1 of this section, and modifying the landfill permit in accordance with 9VAC20-81-600 F 2, the owner or operator may proceed with the implementation of the remedy in accordance with subdivision E 1 of this section.

f. Evaluation and response. The owner or operator shall provide an evaluation of the performance of the implemented presumptive remedy every three years, unless an alternate schedule is approved by the director, in a Corrective Action Site Evaluation report containing, at a minimum, the following information:

b. Inclusion of the unit will enhance implementation of effective, protective, and reliable remedial actions for the facility.

3. Consolidation or placement of remediation wastes into a designated RWMU does not constitute creation of a unit subject to the siting, design, and operation requirements of Part III (9VAC20-81-120, 9VAC20-81-130, and 9VAC20-81-140) and the permitting requirements of Part V (9VAC20-81-400 et seq.) of this chapter.

4. The applicable requirements for groundwater monitoring and closure under 9VAC20-81-250 and 9VAC20-81-160 will continue to apply to the RWMU.

B. Criteria for designating RWMUs. The director will designate an RWMU if he finds that:

1. The RWMU shall facilitate the implementation of reliable, protective and cost-effective remedies;

2. Waste management activities associated with the RWMU shall not create unacceptable risks to humans or to the environment resulting from exposure to solid wastes and solid waste constituents;

3. If an inclusion of uncontaminated areas of the facility into an RWMU is requested, such an inclusion will be more protective than management of such wastes at contaminated areas of the facility;

4. Areas within the RWMU where wastes remain in place after closure of the RWMU shall be managed and contained so as to minimize future releases, to the extent practicable;

5. The RWMU shall expedite the timing of the remedial activity implementation when appropriate and practicable;

6. The RWMU shall enable the use, when appropriate, of treatment technologies (including innovative treatment technologies) to enhance the long-term effectiveness of remedial actions by reducing the toxicity, mobility, or volume of wastes that will remain in place after closure of the RWMU; and

7. The RWMU shall, to the extent practicable, minimize the land area of the facility upon which wastes will remain in place after closure of the RWMU.

C. Requirements. The director will specify the requirements for RWMUs to include, but not be limited to, the following:

4. Closure and postclosure post-closure care requirements:

a. Closure of RWMUs shall:

(1) Minimize the need for further maintenance; and

(2) Control, minimize, or eliminate, to the extent necessary to protect human health and the environment, for areas where wastes remain in place, postclosure post-closure escape of solid waste, solid waste constituents, leachate, contaminated run-off runoff, or waste decomposition products to the ground, surface waters, or the atmosphere.

b. Requirements for closure of an RWMU shall include the following, as appropriate and deemed necessary by the director for a given RWMU:

(1) Requirements for excavation, removal, treatment, or containment of wastes;

(2) For areas in which wastes will remain in place after closure of the RWMU, requirements for capping of such areas; and

(3) Requirements for decontamination of equipment, devices, and structures in remediation waste management activities within the RWMU.

c. In establishing specific closure requirements for RWMUs, the director will consider the following factors:

(1) RWMU characteristics;

(2) Volume of waste that remains in place after closure;

(3) Potential for releases from the RWMU;

(4) Physical and chemical characteristics of the waste;

(5) Hydrological and other relevant environmental conditions at the facility that may influence the migration of any potential or actual releases; and

(6) Potential for exposure of humans and environmental receptors if releases were to occur from the RWMU.

d. Postclosure Post-closure requirements as necessary to protect human health and the environment to include, for areas where wastes will remain in place, monitoring and maintenance activities and the frequency with which such activities shall be performed in order to ensure the integrity of any final cap, final cover, or other containment system.

5. The director will document the rationale for designating RWMUs.

6. The designation of an RWMU does not change the department's existing authority to address clean-up cleanup levels, media specific points of compliance to be applied to remediation at a facility, or other remedy selection decisions.

D. Temporary units.

1. Temporary tanks and container storage areas may be used for treatment or storage of remediation wastes during remedial activities, if the director determines that design, operating, or closure standards applicable to RWMUs may be replaced by alternative requirements that are protective of human health and the environment.

2. Any temporary unit to which alternative requirements are applied shall be:

a. Located within the facility boundary; and

b. Used only for the treatment or storage of remediation wastes.

Such requirements shall be set forth in the final permit issued by the department. The permit applicant by accepting the permit, agrees to the specified periodic inspections.

D. Compliance with a valid permit during its term constitutes compliance, for purposes of enforcement, with the Virginia Waste Management Act. However, a permit may be modified, revoked and reissued, or revoked for cause as set forth in 9VAC20-81-570 and 9VAC20-81-600.

E. The issuance of a permit does not convey any property rights of any sort, or any exclusive privilege.

F. The issuance of a permit does not authorize any injury to persons or property or invasion of other private rights, or any infringement of federal, Commonwealth, or local law or regulations.

G. A permit may be transferred by the permittee to a new owner or operator only if the permit has been revoked and reissued, or a minor modification made to identify the new permittee and incorporate such other requirements as may be necessary. Upon presentation of the financial assurance proof required by 9VAC20-70 by the new owner, the department will release the old owner from his closure and financial responsibilities and acknowledge existence of the new or modified permit in the name of the new owner.

H. This section provides for the approval of permits or permit modifications that include a time allowance for the permittee to achieve the new standards contained in the approved permit or permit modification.

1. The permit may specify a compliance schedule of compliance leading to compliance with this chapter.

a. Any schedules of compliance under this subsection shall require compliance as soon as possible.

b. Except as otherwise provided, if a permit establishes a compliance schedule of compliance that exceeds one year from the date of permit issuance, the schedule shall set forth interim requirements and the dates for their achievement.

(1) The time between interim dates shall not exceed one year; and

(2) If the time necessary for completion of any interim requirement is more than one year and is not readily divisible into stages of completion, the permit shall specify interim dates for the submission of reports of progress toward completion of the interim requirements and indicate a projected completion date.

c. The permit shall be written to require that no later than 14 days following each interim date and the final date of compliance, a permittee shall notify the department, in writing, of his compliance or noncompliance with the interim or final requirements.

2. A permit applicant or permittee may cease conducting regulated activities (by receiving a terminal volume of solid waste, and, in case of treatment or storage facilities, closing pursuant to applicable requirements, or, in case of disposal facilities, closing and conducting postclosure post-closure care pursuant to applicable requirements) rather than continue to operate and meet permit requirements as follows:

a. If the permittee decides to cease conducting regulated activities at a specified time for a permit that has already been issued:

(1) The permit may be modified to contain a new or additional schedule leading to timely cessation of activities; or

(2) The permittee shall cease conducting permitted activities before noncompliance with any interim or final compliance schedule requirement already specified in the permit.

b. If the decision to cease conducting regulated activities is made before the issuance of a permit whose terms will include the termination date, the permit shall contain a schedule leading to termination that will ensure timely compliance with applicable requirements.

c. If the permittee is undecided whether to cease conducting regulated activities, the director may issue or modify a permit to continue two schedules as follows:

(1) Both schedules shall contain an identical interim deadline requiring a final decision on whether to cease conducting regulated activities no later than a date that ensures sufficient time to comply with applicable requirements in a timely manner if the decision is to continue conducting regulated activities;

(2) One schedule shall lead to timely compliance with applicable requirements;

(3) The second schedule shall lead to cessation of regulated activities by a date that will ensure timely compliance with applicable requirements; and

(4) Each permit containing two schedules shall include a requirement that, after the permittee has made a final decision, he shall follow the schedule leading to compliance if the decision is to continue conducting regulated activities, and follow the schedule leading to termination if the decision is to cease conducting regulated activities.

d. The applicant's decisions to cease conducting regulated activities shall be evidenced by a firm public commitment satisfactory to the department, such as a resolution of the board of directors of a corporation.

Notice of the hearing shall be delivered at the conference or sent at the time the permit is suspended. Any person whose permit is suspended by the director shall cease activity for which permit was issued until the permit is reinstated by the director or by a court.

9VAC20-81-600. Modification of permits.

A. Permits may be modified at the request of any interested person or upon the director's initiative. However, permits may only be modified for the reasons specified in subsections E and F of this section. All requests shall be in writing and shall contain facts or reasons supporting the request. Any permit modification authorizing expansion of an existing sanitary landfill shall incorporate the conditions required for a disposal capacity guarantee in § 10.1-1408.1 P of the Code of Virginia. This provision does not apply to permit applications from one or more political subdivisions that will only accept waste from within those political subdivisions' jurisdiction or municipal solid waste generated within other political subdivisions pursuant to an interjurisdictional agreement.

B. If the director decides the request is not justified, he shall send the requester a response providing justification for the decision.

C. If the director tentatively decides to modify, he shall prepare a draft permit incorporating the proposed changes. The director may request additional information and may require the submission of an updated permit application. In a permit modification under subsection E of this section, only those conditions to be modified shall be reopened when a new draft permit is prepared. All other aspects of the existing permit shall remain in effect. During any modification proceeding the permittee shall comply with all conditions of the existing permit until the modified permit is issued.

D. When the director receives any information, he may determine whether or not one or more of the causes listed for modification exist. If cause exists, the director may modify the permit on his own initiative subject to the limitations of subsection E of this section and may request an updated application if necessary. If a permit modification satisfies the criteria in subsection F of this section for minor modifications, the permit may be modified without a draft permit or public review. Otherwise, a draft permit shall be prepared and other appropriate procedures followed.

E. Causes for modification. The director may modify a permit upon his own initiative or at the request of a third party:

1. When there are material and substantial alterations or additions to the permitted facility or activity that occurred after permit issuance that justify the application of permit conditions that are different or absent in the existing permit;

2. When there is found to be a possibility of pollution causing significant adverse effects on the air, land, surface water, or groundwater;

3. When an investigation has shown the need for additional equipment, construction, procedures and testing to ensure the protection of the public health and the environment from adverse effects;

4. If the director has received information pertaining to circumstances or conditions existing at the time the permit was issued that was not included in the administrative record and would have justified the application of different permit conditions, the permit may be modified accordingly if in the judgment of the director such modification is necessary to prevent significant adverse effects on public health or the environment;

5. When the standards or regulations on which the permit was based have been changed by promulgation of amended standards or regulations or by judicial decision after the permit was issued;

6. When the director determines good cause exists for modification of a compliance schedule, such as an act of God, strike, flood, or material shortage or other events over which the permittee has little or no control and for which there is no reasonably available remedy;

7. When a modification of a closure plan is required under 9VAC20-81-160, 9VAC20-81-360, or 9VAC20-81-800 and the permittee has failed to submit a permit modification request within the specified period;

8. When the corrective action program specified in the permit under 9VAC20-81-260 or 9VAC20-81-800 has not brought the facility into compliance with the groundwater protection standard within a reasonable period of time; or

9. When cause exists for revocation under 9VAC20-81-570 and the director determines that a modification is more appropriate.

F. Permit modification at the request of the permittee.
