2. If the permittee knows in advance of the need for a bypass, he shall notify the department promptly at least 10 days prior to the bypass. After considering its adverse effects, the board department may approve an anticipated bypass if:

a. The bypass will be unavoidable to prevent loss of human life, personal injury, or severe property damage ("severe property damage" means substantial physical damage to property, damage to the treatment facilities which causes them to become inoperable, or substantial and permanent loss of natural resources which can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by delays in production); and

b. There are no feasible alternatives to bypass such as the use of auxiliary treatment facilities, retention of untreated waste, or maintenance during normal periods of equipment downtime. However, if bypass occurs during normal periods of equipment downtime or preventive maintenance and in the exercise of reasonable engineering judgment the permittee could have installed adequate backup equipment to prevent such bypass, this exclusion shall not apply as a defense.

3. If an unplanned bypass occurs, the permittee shall notify the department as soon as possible, but in no case later than 24 hours, and shall take steps to halt the bypass as early as possible. This notification will be a condition for defense to an enforcement action that an unplanned bypass met the conditions in subdivision 2 of this subsection and in light of the information reasonably available to the owner at the time of the bypass.

K. Upset. A permittee may claim an upset as an affirmative defense to an action brought for noncompliance. In any enforcement proceedings a permittee shall have the burden of proof to establish the occurrence of any upset. In order to establish an affirmative defense of upset, the permittee shall present properly signed, contemporaneous operating logs or other relevant evidence that shows:

1. That an upset occurred and that the cause can be identified;

2. That the permitted facility was at the time being operated efficiently and in compliance with proper operation and maintenance procedures;

3. That the 24-hour reporting requirements to the department were met; and

4. That the permittee took all reasonable steps to minimize or correct any adverse impact on state waters resulting from noncompliance with the VPA permit.

L. Signature requirements. All applications, reports, or information submitted to the department shall be signed and certified as required in 9VAC25-32-70.

M. Transfers. A VPA permit is not transferable to any person except after notice to the department according to 9VAC25-32-230. The board department may require modification or revocation and reissuance of the VPA permit to change the name of the permittee and incorporate such other requirements as may be necessary.

9VAC25-32-90. Conditions applicable to publicly or privately owned sewage treatment works.

A. Publicly or privately owned sewage treatment works shall provide adequate notice to the department of any substantial change in quantity or quality of pollutants being introduced into the privately or publicly owned sewage treatment works and any anticipated impact the change may have on such treatment works.

B. When the monthly average flow influent to a POTW or PVOTW reaches 95% of the design capacity authorized by the VPA permit for each month of any consecutive three-month period, the owner shall within 30 days notify the department in writing and within 90 days submit a plan of action for ensuring continued compliance with the terms of the VPA permit.

1. The plan shall include the necessary steps and a prompt schedule of implementation for controlling any current problem, or any problem which could reasonably be anticipated, resulting from high influent flows.

2. Upon receipt of the owner's plan of action, the board department shall notify the owner whether the plan is approved or disapproved. If the plan is disapproved, such notification shall state the reasons and specify the actions necessary to obtain approval of the plan.

3. Failure to submit an adequate plan in a timely manner shall be deemed a violation of the VPA permit.

9VAC25-32-100. Establishing limitations and other VPA permit conditions.

A. In addition to the conditions established in 9VAC25-32-80 and 9VAC25-32-90, each VPA permit shall include conditions meeting the following requirements where applicable.

1. Determination of limitations. VPA permit limitations and conditions shall be established based on the nature of the pollutant management activity in order to ensure compliance with technology-based limitations, water quality standards, the law and all regulations promulgated thereunder. These limitations and conditions may include, but are not limited to, duration of VPA permits, monitoring requirements, limitations to control toxic pollutants, best management practices and schedules of compliance.

2. Duration of VPA permits. VPA permits issued under this regulation shall have an effective date and an expiration date which will determine the life of the VPA permit. VPA permits shall be effective for a fixed term not to exceed 10 years as specified in the VPA permit. The term of the VPA permits shall not be extended by modification beyond the maximum duration. The VPA permit shall expire at the end of the term unless an application for a new VPA permit has been timely filed as required by this chapter and the board department is unable, through no fault of the permittee, to issue a new VPA permit before the expiration date of the previous VPA permit.

B. Monitoring requirements.

1. All VPA permits may specify:

a. Requirements concerning the proper use, maintenance and installation, when appropriate, of monitoring equipment or methods;

b. Required monitoring including type, intervals, and frequency sufficient to yield data which are representative of the monitored activity and including, when appropriate, continuous monitoring; and

c. Applicable reporting requirements based upon the impact of the regulated activity on water quality.

2. VPA permits may include requirements to report monitoring results with a frequency dependent on the nature and effect of the pollutant management activity.

3. In addition, the following monitoring requirements may be included in the VPA permits:

a. Mass or other measurements specified in the VPA permit for each pollutant of concern;

b. The volume of waste, wastewater, biosolids, or sludge managed by the activity; and

c. Other measurements as appropriate.

C. Best Management Practices (BMPs). The VPA permit shall require the use of BMPs to control or abate pollutants where numeric limits are infeasible, and the VPA permit may include BMPs in addition to numeric limits where BMPs are necessary to achieve limitations and standards or to carry out the purpose and intent of the law.

D. Sludge disposal. The VPA permit shall include, where appropriate, specific requirements for disposal of all sludge.

E. Biosolids land application. Where, because of site-specific conditions, including soil type, identified during the permit application review process, the department determines that special requirements are necessary to protect the environment or the health, safety or welfare of persons residing in the vicinity of a proposed land application site, the department may incorporate in the permit at the time it is issued reasonable special conditions regarding setback distances, transportation routes, slope, material source, methods of handling and application, and time of day restrictions exceeding those required by this regulation. The permit applicant shall have at least 14 days in which to review and respond to the proposed conditions.

F. Schedules of compliance. The VPA permit may specify a schedule, when appropriate, leading to compliance with the VPA permit as soon as possible. When schedules of compliance are applicable the following shall be incorporated:

1. Schedule or schedules of compliance shall require the permittee to take specific steps where necessary to achieve expeditious compliance with the VPA permit;

2. The schedule of compliance shall set forth interim time periods not more than one year apart for the submission of reports of progress toward completion of each requirement; and

3. Schedule or schedules of compliance may be modified by modification of the VPA permit for good cause beyond the control of the permittee (e.g., act of God, strike, flood, material shortage).

9VAC25-32-110. Draft VPA permit formulation.

A. Upon receipt of a complete application, the board department shall make a decision to tentatively issue the VPA permit or deny the application. If a tentative decision is to issue the VPA permit then a draft VPA permit shall be prepared in advance of public notice. The following tentative determinations shall be incorporated into a draft VPA permit:

1. Conditions, limitations, standards and other requirements applicable to the VPA permit;

2. Compliance schedules where applicable; and

3. Monitoring requirements.

B. If the tentative decision is to deny the application, the board department shall advise the owner of that decision and of the requirements necessary to obtain approval. The owner may withdraw the application prior to board department action. If the application is not withdrawn or modified to contain conditions necessary for tentative approval to issue, the board department shall provide public notice and opportunity for a public hearing prior to board department action on a recommendation to deny the application.

C. This section does not apply to requests for coverage under a general VPA permit.

9VAC25-32-130. Continuation of expiring VPA permits.

A. Expiring VPA permits are automatically continued pending issuance of a new VPA permit if:

1. The permittee has submitted a timely and complete application as required by this chapter, unless the board department has given permission for a later submittal, which shall not extend beyond the expiration date of the original VPA permit; and

2. The board department is unable, through no fault of the permittee, to issue a new VPA permit before the expiration date of the previous VPA permit.

B. Continued VPA permits remain effective and enforceable against the permittee.

9VAC25-32-140. Public notice of VPA permit action and public comment period.

A. Draft VPA permits.

1. Every draft VPA permit shall be given public notice, paid for by the owner, by publication once a week for two successive weeks in a newspaper of general circulation in the area affected by the pollutant management activity except for animal feeding operations as defined in 9VAC25-32-10, when the modifications are to the nutrient management plan.

2. Interested persons shall have a period of at least 30 days following the date of the initial newspaper public notice to submit written comments on the tentative decision and to request a public hearing.

3. The contents of the public notice of an application for a VPA permit shall include:

a. The name and address of the applicant. If the location of the pollutant management activity differs from the address of the applicant the notice shall also state the location of the pollutant management activity including storage and land application sites;

b. A brief description of the business or activity conducted at the facility;

c. A statement of the tentative determination to issue or deny a VPA permit;

d. A brief description of the final determination procedure;

B. VPA permit application.

1. Upon receipt of an application for the issuance of a new or modified permit, the department shall notify in writing the locality wherein the pollutant management activity does or is proposed to take place. This notification shall, at a minimum, include:

a. The name of the applicant;

b. The nature of the application and proposed pollutant management activity;

c. The availability and timing of any comment period; and

d. Upon request, any other information known to, or in the possession of, the board or the department regarding the application except as restricted by 9VAC25-32-150.

2. Whenever the department receives an application for a new permit for land application of biosolids or land disposal of treated sewage, stabilized sewage sludge, or stabilized septage, or an application to reissue with the addition of sites increasing acreage by 50% or more of that authorized in the initial permit, the department shall establish a date for a public meeting to discuss technical issues relating to proposals for land application of biosolids or land disposal of treated sewage, stabilized sewage sludge or stabilized septage. The department shall give notice of the date, time, and place of the public meeting and a description of the proposal by publication in a newspaper of general circulation in the city or county where the proposal is to take place. Public notice of the scheduled meeting shall occur no fewer than seven nor more than 14 days prior to the meeting. The department shall not issue the permit until the public meeting has been held and comment has been received from the local governing body or until 30 days have lapsed from the date of the public meeting.

3. Following the submission of an application for a new permit for land application of biosolids or land disposal of treated sewage, stabilized sewage sludge, or stabilized septage, the department shall make a good faith effort to notify or cause to be notified persons residing on property bordering the sites that contain the proposed land application fields. This notification shall be in a manner selected by the department. For the purposes of this subsection, "site" means all contiguous land under common ownership, but which may contain more than one tax parcel.

4. Public notice shall not be required for submission or approval of plans and specifications or conceptual engineering reports not required to be submitted as part of the application.

C. Following the submission of an application to add a site that is not contiguous to sites included in an existing permit authorizing the land application of biosolids:

1. The department shall notify persons residing on property bordering such site and shall receive written comments from those persons for a period of 30 days. Based upon written comments, the department shall determine whether additional site-specific requirements should be included in the authorization for land application at the site.

2. An application for any permit amendment to increase the acreage authorized by the initial permit by 50% or more shall be considered a major modification and shall be treated as a new application for purposes of public notice and public hearings. The increase in acreage for the purpose of determining the need for the public meeting is the sum of all acreage that has been added to the permit since the last public meeting, plus that proposed to be added.

D. Before issuing any permit, if the board department finds that there are localities particularly affected by the permit, the board department shall:

1. Publish, or require the applicant to publish, a notice in a local paper of general circulation in the localities affected at least 30 days prior to the close of any public comment period. Such notice shall contain a statement of the estimated local impact of the proposed permit, which at a minimum shall include information on the specific pollutants involved and the total quantity of each which may be discharged; and

2. Mail, by electronic or postal delivery, the notice to the chief elected official and chief administrative officer and planning district commission for those localities.

Written comments shall be accepted by the board department for at least 15 days after any public hearing on the permit, unless the board votes to shorten department shortens the period. For the purposes of this section, the term "locality particularly affected" means any locality which bears any identified disproportionate material water quality impact which would not be experienced by other localities.

9VAC25-32-160. Conditions requested by other government agencies.

If during the comment period any other state agency with jurisdiction over fish, wildlife, or public health advises the department in writing that the imposition of specified conditions upon the VPA permit is necessary to avoid substantial impairment of human health or of fish, shellfish, or wildlife resources, the board department shall consider the inclusion of the specified conditions in the VPA permit. If any conditions requested are not included in the VPA permit, the agency making the request shall be notified of the reasons for not including the conditions.

9VAC25-32-170. Public comments and hearings.

A. A comment period of at least 30 days following the initial date of the newspaper public notice of the formulation of a draft VPA permit shall be provided. During this period any interested persons may submit written comments on the draft VPA permit and may request a public hearing. A request for a public hearing shall be in writing and shall state the nature of the issues to be raised pursuant to the board's Procedural Rule No. 1 (9VAC25-230-10 et seq.), or its successor 9VAC25-32-175. All comments shall be considered by the board department in preparing the final VPA permit and shall be responded to in writing.

B. The board department may hold a public hearing on any permit action. The board department shall hold a public hearing where there is a significant degree of public interest relevant to a draft VPA permit pursuant to 9VAC25-32-175. Public notice of that hearing shall be given as specified in 9VAC25-32-180. Nothing in this subsection shall relieve the board department of the requirement to hold a hearing where a hearing is required by applicable law or regulation.

C. Any hearing convened pursuant to this section will be held in the geographical area of the proposed pollutant management activity, or in another appropriate area. Related groups of VPA permit applications may be considered at any such hearing.

D. If changes are made to the VPA permit based on public comments, the permittee and all persons who commented will be notified of the changes and the reasons for the changes. No further public notice is required.

E. Any owner aggrieved by any action of the board department taken without a formal hearing, or by inaction of the board department, may demand in writing a formal hearing pursuant to § 62.1-44.25 of the Code of Virginia.

F. Proceedings at, and the decision from, the public hearing will be governed by the board's Procedural Rule No. 1 - Public and Formal Hearing Procedures (9VAC25-230-10 et seq) or its successor, and the decision from the public hearing will be governed by 9VAC25-32-176.

9VAC25-32-210. Causes for termination.

A. The following are causes for terminating a VPA permit during its term, or for denying a VPA permit renewal application, after public notice and opportunity for a public hearing:

1. The permittee has violated any regulation of the board or order of the board department, any condition of a VPA permit, any provision of the law, or any order of a court, where such violation results in a release of harmful substances into the environment or poses a substantial threat of release of harmful substances into the environment or presents a hazard to human health or the violation is representative of a pattern of serious or repeated violations which, in the opinion of the board department, demonstrates the permittee's disregard for or inability to comply with applicable laws, regulations or requirements;

2. The permittee's failure to disclose fully all relevant material facts, or the permittee's misrepresentation of any relevant material facts in applying for a VPA permit, or in any other report or document required under the law or this chapter;

3. A determination that the permitted activity endangers human health or the environment and can only be regulated to acceptable levels by VPA permit modification or termination; or

4. There exists a material change in the basis on which the VPA permit was issued that requires either a temporary or a permanent reduction or elimination of any pollutant management activity controlled by the VPA permit necessary to protect human health or the environment.

B. In addition to causes for terminating a VPA permit specified in subsection A of this section, causes for terminating a VPA permit issued for land application, marketing and distribution of biosolids shall include:

1. Failure to comply with the conditions of the permit.

2. Violation of Chapter 3.1 (§ 62.1-44.2 et seq.) of Title 62.1 of the Code of Virginia or of any provisions of this regulation.

3. Change in ownership.

4. Abandonment of the facilities.

C. A VPA permit may be terminated without public notice and opportunity for a hearing when the termination is mutually agreed to by the permittee and the board department.

9VAC25-32-230. Transfer of VPA permits.

A. Transfer by modification. Except as provided for under automatic transfer in subsection B of this section, a VPA permit shall be transferred only if the VPA permit has been modified to reflect the transfer or has been revoked and reissued to the new owner.

B. Automatic transfer. Any VPA permit shall be automatically transferred to a new owner if:

1. The current owner notifies the department 30 days in advance of the proposed transfer of the title to the facility or property;

2. The notice to the department includes a written agreement between the existing and proposed new owner containing a specific date of transfer of VPA permit responsibility, coverage and liability between them; and

3. The board department does not within the 30-day time period notify the existing owner and the proposed owner of its intent to modify or revoke and reissue the VPA permit.

9VAC25-32-240. Minor modification.

A. Upon request of the permittee, or upon board department initiative with the consent of the permittee, minor modifications may be made in the VPA permit without following the public involvement procedures.

B. Minor modification may only:

1. Correct typographical errors;

3. Change an interim compliance date in a schedule of compliance to no more than 120 days from the original compliance date and provided it will not interfere with the final compliance date;

4. Allow for a change in name, ownership or operational control when the board department determines that no other change in the VPA permit is necessary, provided that a written agreement containing a specific date for transfer of VPA permit responsibility, coverage and liability from the current to the new permittee has been submitted to the department;

5. Delete the listing of a land application site when the pollutant management activity is terminated and does not result in an increase of pollutants which would exceed VPA permit limitations;

6. Reduce VPA permit limitations to reflect a reduction in the permitted activity when such reduction results from a shutdown of processes or pollutant generating activities or from connection of the permitted activity to a POTW;

7. Change plans and specifications where no other changes in the VPA permit are required;

8. Authorize treatment facility expansions, production increases or process modifications which will not cause a significant change in the quantity of pollutants being managed or a significant change in the nature of the pollutant management activity; or

9. Delete VPA permit limitation or monitoring requirements for specific pollutants when the activities generating these pollutants are terminated.

C. An application for any permit amendments to increase the acreage authorized by the initial permit shall not be considered a minor modification and shall require the public involvement procedures outlined in 9VAC25-32-140 C.

9VAC25-32-250. Animal feeding operations.

A. All animal feeding operations shall maintain no point source discharge of pollutants to surface waters except in the case of a storm event greater than the 25-year, 24-hour storm. Animal feeding operations having 300 or more animal units utilizing a liquid manure collection and storage system or having 200 or more animal units of poultry are pollutant management activities subject to the VPA permit program. Two or more animal feeding operations under common ownership are a single animal feeding operation for the purpose of determining the number of animals at an operation if they adjoin each other or if they use a common area or system for the disposal of wastes.

B. Case-by-case determination.

1. The board department may determine that any animal feeding operation that does not otherwise qualify for coverage under the VPA general permit and has not been required to obtain a VPDES permit be required to obtain an individual VPA permit upon determining that it is a potential or actual contributor of pollution to state waters. In making this determination the following factors shall be considered:

a. The size of the operation;

b. The location of the operation relative to state waters;

c. The means of conveyance of animal wastes and process waters into state waters;

d. The slope, vegetation, rainfall, and other factors affecting the likelihood or frequency of discharge of animal wastes and process waste waters into state waters;

e. The compliance history and the ability to make corrections in order to comply with the VPA general permit conditions;

f. The means of storage, treatment, or disposal of animal wastes; and

g. Other relevant factors.

2. A VPA permit application shall not be required for an animal feeding operation subject to subdivision 1 of this subsection until the board department has conducted an on-site inspection of the operation and determined that the operation shall be regulated under the VPA permit program.

9VAC25-32-260. General VPA permits.

The board may issue a general VPA permit in accordance with the following:

1. Sources. A general VPA permit may be written to regulate a category of pollutant management activities that:

a. Involve the same or similar types of operations;

b. Manage the same or similar types of wastes;

c. Require the same VPA permit limitations or operating conditions;

d. Require the same or similar monitoring; and

e. In the opinion of the board, are more appropriately controlled under a general VPA permit than under individual VPA permits.

2. Administration.

a. General VPA permits will be issued, modified, revoked and reissued, or terminated pursuant to the law and the Administrative Process Act (§ 2.2-4000 et seq. of the Code of Virginia).

b. The board department may require any person operating under a general VPA permit to apply for and obtain an individual VPA permit. Interested persons may petition the board department to take action under this subdivision. Cases where an individual VPA permit may be required include the following:

(1) Where the pollutant management activity is a significant contributor of pollution;

(2) Where the owner is not in compliance with the conditions of the general VPA permit;

(3) When a water quality management plan containing requirements applicable to the pollutant management activity is approved; or

(4) When a permitted activity no longer meets the general VPA permit conditions.

c. Any owner operating under a general VPA permit may request to be excluded from the coverage of the general VPA permit by applying for an individual VPA permit.

d. When an individual VPA permit is issued to an owner the applicability of the general VPA permit to the individual permittee is automatically terminated on the effective date of the individual VPA permit.

e. When a general VPA permit is issued which applies to an owner already covered by an individual VPA permit, such owner may request exclusion from the provisions of the general VPA permit and subsequent coverage under an individual VPA permit.

f. A general VPA permit may be revoked as to an individual owner for any of the reasons set forth in 9VAC25-32-210 or subdivision 2 b of this section subject to appropriate opportunity for a hearing.

9VAC25-32-270. Control of disposal of pollutants into wells.

A. No right to dispose of pollutants into wells shall exist under this regulation, except as authorized pursuant to a VPA permit issued by the department or VPA general permit issued as a regulation adopted by the board.

B. Whenever an applicant for a VPA permit proposes to dispose of pollutants into a well or wells, the proposed disposal shall be prohibited, or specific terms and conditions shall be included in the VPA permit which shall control the proposed disposal in order to prevent the pollution of and protect all beneficial uses of state waters, protect the public health and welfare, and require compliance with all applicable water quality standards.

9VAC25-32-280. Enforcement.

A. The board department may enforce the provisions of this regulation by:

1. Issuing directives in accordance with the law;

2. Issuing special orders in accordance with the law;

1. The board department will investigate citizen complaints and provide written response to all signed, written complaints from citizens concerning matters within the board's department's purview;

2. The board department will not oppose intervention in any civil enforcement action when such intervention is authorized by statute or Supreme Court rule, or in any administrative enforcement action when authorized by the board's Procedural Rule; and

3. At least 30 days prior to the final settlement of any civil enforcement action or the issuance of any consent special order, the board department will publish public notice of such settlement or order in a newspaper of general circulation in the county, city or town in which the pollutant management activity is located, and in the Virginia Register of Regulations. This notice will identify the owner, specify the enforcement action to be taken and specify where a copy of the settlement or order can be obtained. Appeals will be public noticed in accordance with Procedural Rule No. 1 - Public and Formal Hearing Procedures (9VAC25-230-10 et seq.). A consent special order is a special order issued without a public hearing and with the written consent of the affected owner. For the purpose of this chapter, an emergency special order is not a consent special order. The board department shall consider all comments received during the comment period before taking final action.

C. When a VPA permit is amended solely to reflect a new owner, and the previous owner had been issued a consent special order that at the time of VPA permit amendment was still in full force and effect, a consent special order issued to the new owner does not have to go to public notice provided that:

1. The VPA permit amendment does not have to go to public notice, and

2. The terms of the new consent order are the same as issued to the previous owner.

D. Notwithstanding subdivision 3 of this subsection, a special order may be issued by agreement at a board meeting the department without further notice when a public hearing has been scheduled to issue a special order, to the affected owner, whether or not the public hearing is actually held.

B. A separate biosolids use permit shall be issued for each political jurisdiction (county or city) where land application is proposed.

C. No person shall land apply Class B biosolids on any land in Virginia unless that land has been identified in an application to issue, reissue or modify a permit and approved by the board department.

D. No person shall land apply, market, or distribute biosolids in Virginia unless the biosolids source has been approved by the board department.

9VAC25-32-315. Additional and more stringent requirements.

A. On a case-by-case basis, the board department may impose requirements for the use of biosolids or the disposal of sewage sludge in addition to or more stringent than the requirements in this part when necessary to protect human health and the environment from any adverse effect of a pollutant in the biosolids or sewage sludge.

B. Nothing in this part precludes the authority of another state agency, political subdivision of Virginia, or an interstate agency with respect to the use of biosolids or disposal of sewage sludge.

C. For biosolids land application where, because of site specific conditions, including soil type, identified during the permit application review process, the department determines that special requirements are necessary to protect the environment or the health, safety, or welfare of persons residing in the vicinity of a proposed land application site, the department may incorporate in the permit at the time it is issued reasonable special conditions regarding setback distances, transportation routes, slope, material source, methods of handling and application, and time of day restrictions exceeding those required by this regulation. The permit applicant shall have at least 14 days in which to review and respond to the proposed conditions.

9VAC25-32-330. Variances.

A. The board department may grant a variance to a procedural, design, or operational regulation by following the appropriate procedures set forth in this section.

B. Requirements for a variance. The board department may grant a variance if it finds that the hardship imposed outweighs the benefits that may be received by the public and that the granting of such variance does not subject the public to unreasonable health risks or environmental pollution.

C. Application for a variance. Any owner may apply in writing for a variance. The application shall be submitted to the appropriate regional office for evaluation. The application shall include:

1. A citation of the regulation from which a variance is requested.

2. The nature and duration of variance requested.

3. A statement of the hardship to the owner and the anticipated impacts to the public health and welfare if a variance were granted.

4. Suggested conditions that might be imposed on the granting of a variance that would limit its detrimental impact on public health and welfare.

5. Other information, if any, believed to be pertinent by the applicant.

6. Such other information as may be required to make the determination in accordance with subsection B of this section.

D. Consideration of a variance.

1. The board department shall act on any variance request submitted pursuant to this subsection within 90 days of receipt of request.

2. In the board's department's consideration of whether a biosolids use variance should be granted, the board department shall consider such factors as the following:

a. The effect that such a variance would have on the adequate operation of the biosolids use facility, including public nuisance concerns;

b. The cost and other economic considerations imposed by this requirement; and

c. The effect that such a variance would have on the protection of the public health or the environment.

E. Disposition of a variance request.

1. The board department may grant the variance request and if the board department proposes to deny the variance it shall provide the owner an opportunity to an informal proceeding as provided in § 2.2-4019 of the Code of Virginia. Following this opportunity for an informal proceeding the board department may reject any application for a variance by sending a rejection notice to the applicant. The rejection notice shall be in writing and shall state the reasons for the rejection. A rejection notice constitutes a case decision.

2. If the board department proposes to grant a variance request submitted pursuant to this regulation, the applicant shall be notified in writing of this decision. Such notice shall identify the variance, the biosolids use facility involved, and shall specify the period of time for which the variance will be effective. Such notice shall provide that the variance will be terminated when the biosolids use facility comes into compliance with the applicable regulation and may be terminated upon a finding by the board department that the biosolids use facility has failed to comply with any requirements or schedules issued in conjunction with the variance. The effective date of the variance shall be 15 days following its issuance.

F. Posting of variances. All variances granted for the design or operation of biosolids use facility are nontransferable. Any requirements of the variance shall become part of the permit for biosolids use subsequently granted by the board department.

9VAC25-32-350. Procedures for obtaining a certificate to construct and certificate to operate.

No owner shall cause or allow the construction, expansion, modification, or operation of facilities necessary for biosolids treatment or storage except in compliance with a certificate to construct (CTC) and a certificate to operate (CTO) issued by the board department in accordance with the Sewage Collection and Treatment Regulations (9VAC25-790).

9VAC25-32-358. Frequency of monitoring.

A. Biosolids.

1. The frequency of monitoring for the pollutants listed in Tables 1 through 5 of 9VAC25-32-356; the pathogen density requirements in 9VAC25-32-675 A and B 2 through B 4; and the vector attraction reduction requirements in 9VAC25-32-685 B 1 through B 4, B 7, and B 8 shall be the frequency in Table 1 of this section.

TABLE 1 FREQUENCY OF MONITORING – LAND APPLICATION
Amount of biosolids(1) (metric tons per 365-day period)	Frequency(2)
Greater than zero but less than 290	Once per year
Equal to or greater than 290 but less than 1,500	Once per quarter (four times per year)
Equal to or greater than 1,500 but less than 15,000	Once per 60 days (six times per year)
Equal to or greater than 15,000	Once per month (12 times per year
Note(1): Either the amount of bulk biosolids applied to the land or the amount of biosolids received by a person who prepares biosolids that is sold or given away in a bag or other container for application to the land (dry weight basis).
Note(2): Sampling shall be conducted at approximately equal intervals at the listed frequencies. Biosolids programs that store biosolids and land apply only during discrete events throughout the year shall schedule sampling events to coincide with application periods. The department may require increased monitoring frequencies, if necessary, to adequately define any significant variability in biosolids quality.

2. After the biosolids has been monitored for two years at the frequency in Table 1 of this section, the board department may reduce the frequency of monitoring for pollutant concentrations and for the pathogen density requirements in 9VAC25-32-675 A 5 b and c.

B. Domestic septage. If the vector attraction reduction requirements in 9VAC25-32-685 B 12 are met when domestic septage is applied to agricultural land, forest, or a reclamation site, each container of domestic septage applied to the land shall be monitored for compliance with those requirements.

9VAC25-32-400. Additional monitoring.

A. The department may require that additional site specific monitoring be performed by the holder of the permit for any biosolids land application practice regardless of frequency of application or size of the application area. Such requirements may occur in situations in which groundwater contamination, surface runoff, soil toxicity, health hazards or nuisance conditions are identified as an existing problem or potential problem as a result of biosolids use operations. Additional monitoring may include, but is not limited to, groundwater, surface water, crop, and soil monitoring.

B. The board department may require the owner or operator of any facility or operation to install, use, and maintain monitoring equipment for internal testing of biosolids quality, to identify and determine the causes of operational problems, and to determine the necessary corrective actions to correct such problems. If this testing is required, test results shall be recorded, compiled, and reported to the department.

C. Additional operational control information may be required on an individual basis by the department.

D. The department may require biosolids to be tested for certain toxic organic compounds prior to agricultural use. If performed and validated, these test results shall be utilized to evaluate the maximum allowable annual loading rate for the tested biosolids. If analytical test results verify that biosolids contains levels of organic chemicals exceeding concentration limits incorporated in federal regulations or standards, appropriate restrictions shall be imposed for agricultural use of those biosolids.

E. Additional parameters may be required for screening purposes such as aluminum (mg/kg), water soluble boron (mg/kg), calcium (mg/kg), manganese (mg/kg), sulfates (mg/kg), and those pollutants for which removal credits are granted.

F. Microbiological testing may be necessary to document the sludge treatment classification (9VAC25-32-675). Microbiological standards shall be verified by the log mean of the analytical results from testing of seven or more samples of the sludge source. Sampling events shall be separated by an appropriate period of time so as to be representative of the random and cyclic variations in sewage characteristics.

9VAC25-32-410. Biosolids management plan.

A. The permit holder shall maintain and implement a Biosolids Management Plan that shall consist of three components:

1. The materials, including site booklets, developed and submitted at the time of permit application or permit modification adding a farm to the permit in accordance with 9VAC25-32-60 F;

b. Sites where land application more frequently than once every three years at greater than 50% of the annual agronomic rate is proposed;

c. Mined or disturbed land sites where land application is proposed at greater than agronomic rates; and

d. Other sites based on site-specific conditions that increase the risk that land application may adversely impact state waters.

2. Where conditions at the land application site change so that it meets one or more of the specific conditions identified in subdivisions 1 a through d of this subsection, an approved nutrient management plan shall be submitted prior to any future land application at the site.

3. The nutrient management plan shall be available for review by the department at the land application site during biosolids land application.

4. Within 30 days after land application at the site has commenced, the permit holder shall provide a copy of the nutrient management plan to the farm operator of the site, the Department of Conservation and Recreation and the chief executive officer or designee for the local government unless they request in writing not to receive the nutrient management plan.

5. The nutrient management plan must be approved by the Department of Conservation and Recreation prior to land application for application sites where the soil test phosphorus levels exceed the values in Table 1 of this section. For purposes of approval, permittees should submit the nutrient management plan to the Department of Conservation and Recreation at least 30 days prior to the anticipated date of land application to ensure adequate time for the approval process.

9VAC25-32-490. Compliance with biosolids use practices of this chapter.

Guidelines set forth in 9VAC25-32-515 through 9VAC25-32-580 of this regulation specify minimum standards for biosolids use for land application, marketing and distribution, including biosolids quality and site specific management practices. Compliance with this chapter will not be required for facilities not including land application, distribution, or marketing, which have received the approval of the Commissioner of the State Department of Health and the State Water Control Board and for which operation has commenced as of January 1, 2008. Such operation of facilities is deemed to be commenced upon issuance of a certificate to operate in accordance with the Sewage Collection and Treatment Regulations (9VAC25-790). However, the board department may impose standards and requirements that are more stringent than those contained in this regulation according to the provisions of 9VAC25-32-100 E, 9VAC25-32-315, and 9VAC25-32-560 B 3. Conformance to local land use zoning and planning should be resolved between the local government and the facility owner or permit holder. Applications submitted for facilities must demonstrate that the facility and biosolids use management practices will adequately safeguard public health and will comply with the certificate and permit requirements, as appropriate. Submissions that are in substantial compliance with this regulation and comply with any additional requirements as noted above will be approved. Justification for biosolids use proposals may be required for those portions of the submitted proposal that differ from these criteria. The owner or owner's agent shall identify and justify noncompliance with specific standards or "shall" criteria that the department identifies, or the applicant, in his judgment, believes to be substantial in nature. The department may request changes in designs that are not in substantial compliance with this regulation and that are not adequately justified by the applicant. The fact that significant work was accomplished on a specific permit application prior to adoption of this regulation shall be a consideration when evaluating applications.

9VAC25-32-530. Land acquisition.

A. When an application to permit land application of biosolids is submitted to the department, the permit applicant shall ensure the continued availability of the land and protection from improper concurrent use during the utilization period.

4. For permits modified in order to incorporate changes to this regulation, the permit holder shall, within 60 days of the effective date of the permit modification, advise the landowner by certified letter of the requirement to provide a new landowner agreement. The letter shall include instructions to the landowner for signing and returning the new landowner agreement, and shall advise the landowner that the permit holder's receipt of such new landowner agreement is required prior to application of biosolids to the landowner's property.

5. The responsibility for obtaining and maintaining the agreements lies with the permit holder. The written agreement shall be submitted to the department with the permit application.

9VAC25-32-540. Transport.

A. Transport routes should follow primary highways, shall avoid residential areas when possible, and shall comply with all Virginia Department of Transportation requirements and standards. Transport vehicles shall be sufficiently sealed to prevent leakage and spillage of biosolids. For biosolids with a solids content of less than 15%, totally closed watertight transport vehicles with rigid tops shall be provided to prevent spillage unless adequate justification is provided to demonstrate that such controls are unnecessary. The board department may also require certain dewatered biosolids exceeding 15% solids content to be handled as liquid biosolids. The minimum information for biosolids transport that shall be supplied in the biosolids management plan is listed in 9VAC25-32-60 F.

B. The permit holder shall be responsible for the prompt cleanup and removal of biosolids spilled during transport. The operations manual shall include a plan for the prevention of spills during transport and for the cleanup and removal of spills. The permit holder shall ensure that its personnel, subcontractors or the drivers of vehicles transporting biosolids for land application shall be properly trained in procedures for spill removal and cleanup.

C. The permit holder shall take appropriate steps to prevent drag-out and track-out of dirt and debris or biosolids from land application sites onto public roads. Where material is transported onto a paved or public road surface, the road surface shall be cleaned thoroughly as soon as practicable, but no later than the end of each day.

D. The permit holder shall promptly report offsite spills to the department, the chief executive officer or designee for the local government and the owner of the facility generating the biosolids. The report shall be made verbally as soon as possible, but no later than 24 hours after the discovery of the spill. After business hours notification may be provided by voicemail, facsimile or email.

E. A written report, which shall include a description of measures taken in response to the spill, shall be submitted by the permit holder to the department, the chief executive officer or designee for the local government, and the owner of the facility generating the biosolids within five working days of the spill. The report may be sent by first class mail, facsimile or email, or it may be hand delivered.

9VAC25-32-550. Storage facilities.

A. No person shall apply to the department for a permit, a variance, or a permit modification authorizing storage of biosolids without first complying with all requirements adopted pursuant to § 62.1-44.19:3 R of the Code of Virginia.

1. On-site storage, or

2. Routine storage. Only routine storage facilities shall be considered a facility under this regulation.

C. All on-site storage and routine storage facilities shall comply with the requirements of this section by 12 months from the effective date of this regulation.

D. On-site storage. On-site storage is the short-term storage of biosolids on a constructed surface within a site approved for land application at a location preapproved by the department. These stored biosolids shall be applied only to sites under the operational control of the same owner or operator of the site where the on-site storage is located. Requirements for on-site storage include the following:

1. The certified land applier shall notify the department within the same working day whenever it is necessary to implement on-site storage. Notification shall include the source or sources, location, and amounts;

2. A surface shall be constructed with sufficient strength to support operational equipment and with a maximum permeability of 10^-7 cm/sec;

3. Storage shall be limited to the amount of biosolids specified in the nutrient management plan to be applied at sites under the operational control of the same owner or operator of the site where the on-site storage is located;

4. If malodors related to the stored biosolids are verified by the department at any occupied dwelling on surrounding property, the problem must be corrected within 48 hours. If the problem is not corrected within 48 hours, the biosolids must be removed from the storage site;

5. All biosolids stored on the on-site storage pad shall be land applied by the 45^th day from the first day of on-site storage;

6. Biosolids storage shall be located to provide minimum visibility from adjacent properties;

7. Best management practices shall be utilized as appropriate to prevent contact with storm water run on or runoff;

8. Stored biosolids are to be inspected by the certified land applier at least every seven days and after precipitation events of 0.1 inches or greater to ensure that runoff controls are in good working order. Observed excessive slumping, erosion, or movement of biosolids is to be corrected within 24 hours. Any ponding or malodor at the storage site is to be corrected. The certified land applier shall maintain documentation of inspections of stored biosolids;

9. The department may prohibit or require additional restrictions for on-site storage in areas of Karst topography and environmentally sensitive sites; and

10. Storage of biosolids shall be managed so as to prevent adverse impacts to water quality or public health.

E. Routine storage. Routine storage is the long-term storage of biosolids at a facility not located at the site of the wastewater treatment plant, preapproved by the department and constructed specifically for the storage of biosolids to be applied at any permitted site. Routine storage facilities shall be provided for all land application projects if no alternative means of management is available during nonapplication periods. No person shall apply to the department for a permit, a variance, or a permit modification authorizing storage of biosolids without first complying with all requirements adopted pursuant to § 62.1-44.19:3 A 5 of the Code of Virginia. Plans and specifications for any surface storage facilities (pits, ponds, lagoons) or aboveground facilities (tanks, pads) shall be submitted as part of the minimum information requirements. The minimum information requirements include:

1. Location.

a. The facility shall be located at an elevation that is not subject to, or is otherwise protected against, inundation produced by the 100-year flood/wave action as defined by U.S. Geological Survey or equivalent information.

b. Storage facilities should be located to provide minimum visibility.

c. All storage facilities located offsite of property owned by the generator shall be provided with a minimum 750-feet setback area. The length of the setback area considered will be the distance measured from the perimeter of the storage facility. Residential uses, high-density human activities and activities involving food preparation are prohibited within the setback area. The board department may reduce the setback requirements based on site-specific factors, such as facility size, topography, prevailing wind direction, and the inclusion of an effective windbreak in the overall design.

2. Design capacity.

a. The design capacity for storage of liquid biosolids shall be sufficient to store a minimum volume equivalent to 60 days or more average production of biosolids and the incidental wastewater generated by operation of the treatment works plus sufficient capacity necessary for: (i) the 25 year-24 hour design storm (incident rainfall and any runoff as may be present); (ii) net precipitation excess during the storage period; and (iii) an additional one foot freeboard from the maximum water level (attributed to the sum of the above factors) to the top berm elevation. Storage capacity of less than that specified above will be considered on a case-by-case basis only if sufficient justification warrants such a reduction.

b. If alternative methods of management cannot be adequately verified, contractors shall provide for a minimum of 30 days of in-state routine storage capacity for the average quantity of biosolids transported into Virginia from out-of-state treatment works generating at least a Class B biosolids.

3. Facility design.

e. Storage facilities shall be of uniform shape (round, square, rectangular) with no narrow or elongated portions.

f. The facilities shall also be designed to permit access of equipment necessary for loading and unloading biosolids, and shall be designed with receiving facilities to allow for even distribution of biosolids into the facility.

g. The design shall also provide for truck cleaning facilities.

4. Monitoring. All biosolids storage facilities shall be monitored in accordance with the requirements of this regulation. Plans and specifications shall be provided for such a monitoring program in accordance with the minimum information specified in 9VAC25-32-60 F and 9VAC25-32-410.

5. Operation.

a. Only biosolids suitable for land application (Class A or B biosolids) shall be placed into permitted routine storage facilities.

b. Storage of biosolids located offsite or remote from the wastewater treatment works during the summer months shall be avoided whenever possible so that the routine storage facility remains as empty as possible during the summer months.

c. Storage facilities shall be operated in a manner such that sufficient freeboard is provided to ensure that the maximum anticipated high water elevation due to any and all design storm inputs is not less than one foot below the top berm elevation.

d. Complete plans for supernatant disposal shall be provided in accordance with 9VAC25-32-60 F. Plans for supernatant disposal may include transport to the sewage treatment works, mixing with the biosolids for land application or land application separately. However, separate land application of supernatant will be regulated as liquid biosolids; additional testing, monitoring and treatment (disinfection) may be required.

e. The facility site shall be fenced to a minimum height of five feet; gates and locks shall be provided to control access. The fence shall be posted with signs identifying the facility. The fence shall not be constructed closer than 10 feet to the outside edge of the facility or appurtenances, to allow adequate accessibility.

9VAC25-32-560. Biosolids utilization methods.

A. Requirements applicable to land application of biosolids.

1. All biosolids application rates, application times and other site management operations shall be restricted as specified in the biosolids management plan. The biosolids management plan shall include a nutrient management plan as required by 9VAC25-32-410 and prepared by a certified nutrient management planner as stipulated in regulations promulgated pursuant to § 10.1-104.2 of the Code of Virginia.

2. Biosolids shall be treated to meet standards for land application as required by Part IX (9VAC25-32-303 et seq.) of this chapter prior to delivery at the land application site. No person shall alter the composition of biosolids at a site approved for land application of biosolids under a Virginia Pollution Abatement Permit. Any person who engages in the alteration of such biosolids shall be subject to the penalties provided in Article 6 (§ 62.1-44.31 et seq.) of Chapter 3.1 of Title 62.1 of the Code of Virginia. The addition of lime or deodorants to biosolids that have been treated to meet standards for land application as required by Part IX (9VAC25-32-303 et seq.) of this chapter shall not constitute alteration of the composition of biosolids. The board department may authorize public institutions of higher education to conduct scientific research on the composition of biosolids that may be applied to land.

B. Agricultural use. Agricultural use of biosolids is the land application of biosolids to cropland or pasture land to obtain agronomic benefits as a plant nutrient source and soil conditioner.

1. Biosolids treatment. As a minimum, biosolids that are applied to the land or incorporated into the soil shall be treated by a Class II pathogen treatment process and shall be treated or managed to provide an acceptable level of vector attraction reduction.

2. Site soils.

a. Depth to bedrock or restrictive layers shall be a minimum of 18 inches.

b. Biosolids application shall not be made during times when the seasonal high water table of the soil is within 18 inches of the ground surface. If Natural Resources Conservation Service soil survey information regarding depth of seasonal water table is not available, the water table depth shall be determined by soil characteristics or water table observations. If the soil survey or such evidence indicates that the seasonal water table can be less than 18 inches below the average ground surface, soil borings shall be conducted within seven days prior to land application operations during periods of high water table for the soil series present to verify the actual water table depth. The use of soil borings and water table depth verification may be required for such sites from November to May (during seasonal high water table elevations) of each year depending on soil type. Constructed channels (agricultural drainage ditches) may be utilized to remove surface water and lower the water table as necessary for crop production and site management.

c. The pH of the biosolids and soil mixture shall be 6.0 or greater at the time of each biosolids application if the biosolids cadmium concentration is greater than or equal to 21 mg/kg. The soil pH must be properly tested and recorded prior to land application operations during which a pH change of one-half unit or more may occur within the zone of incorporation (i.e., use of biosolids containing lime or other alkaline additives at 10% or more of dry solid weight).

d. When soil test pH is less than 5.5 S.U., the land shall be supplemented with lime at the recommended agronomic rate prior to or during biosolids application if the biosolids to be land applied have not been alkaline stabilized.

e. When soil test potassium levels are less than 38 parts per million (Mehlich I analytical procedure or equivalent), the land shall be supplemented with potash at the recommended agronomic rate prior to or during biosolids application.

3. Management practices.

a. Site specific application rates shall not exceed the rates established in the nutrient management plan nor result in exceedance of the cumulative trace element loading rates specified in 9VAC25-32-356 Table 3.

b. Agricultural use of stabilized septage shall be in accordance with the same requirements as biosolids.

c. Infequent application. If biosolids are applied to a field only once in a three-year period, biosolids may be applied such that the total crop needs for nitrogen is not exceeded during a one-year crop rotation period including the production and harvesting of two crops in succession within a consecutive 12-month growing season. The infrequent application rate may be restricted (i) down to 10% of the maximum cumulative loading rate (9VAC25-32-356 Table 3) for cadmium and lead or (ii) to account for all sources of nutrients applied to the site, including existing residuals.

d. Operations.

(1) Field management. The application rate of all application equipment shall be routinely measured as described in a biosolids management plan. Liquid biosolids shall not be applied at rates exceeding 14,000 gallons per acre, per application. Sufficient drying times shall be allowed between subsequent applications. Application vehicles shall be suitable for use on agricultural land. Pasture and hay fields shall be grazed or clipped to a height of approximately six inches prior to biosolids application. Biosolids shall be applied such that uniform application is achieved. If application methods do not result in a uniform distribution of biosolids, additional operational methods shall be employed following application such as dragging with a pasture harrow, followed by clipping if required, to achieve a uniform distribution of the applied biosolids.

(2) Surface incorporation may be required on cropland by the department, or the local monitor with approval of the department, to mitigate malodors when incorporation is practicable and compatible with a soil conservation plan or contract meeting the standards and specifications of the U.S. Department of Agriculture Natural Resources Conservation Service.

(3) Slopes above 15%. Biosolids shall not be applied to site slopes exceeding 15%. This restriction may be waived by the department for the establishment and maintenance of perennial vegetation or based on site specific criteria and BMPs in place in the field.

(4) Biosolids application timing and slope restrictions shall conform to criteria contained in regulations promulgated pursuant to § 10.1-104.2 of the Code of Virginia.

(5) Snow. Biosolids may only be applied to snow-covered ground if the snow cover does not exceed one inch and the snow and biosolids are incorporated within 24 hours of application. If snow melts during biosolids application, incorporation is not necessary.

e. Setback distances.

(1) Setback distances. The land application of biosolids shall not occur within the following minimum setback distance requirements (Table 1 of this section):

1The setback distance to occupied dwellings may be reduced or waived upon written consent of the occupant and landowner of the dwelling. 2The department shall grant to any landowner or resident in the vicinity of a biosolids land application site an extended setback of up to 200 feet from their property line and up to 400 feet from their occupied dwelling upon request from their physician based on medical reasons. In order for an extended setback request to be granted, the request must be submitted to the department in writing on a form provided by the department. A request must be received by the department no later than 48 hours before land application commences on the field affected by the extended setback, and communicated to the permittee no later than 24 hours before land application commences on the field affected by the extended setback. The department may extend a setback distance within 48 hours of land application if requested by the Virginia Department of Health in connection with the landowner or resident's physician. 3Setback distances may be extended beyond 400 feet where an evaluation by the Virginia Department of Health determines that a setback in excess of 400 feet is necessary to prevent specific and immediate injury to the health of an individual. 4The setback distance to property lines may be reduced or waived upon written consent of the landowner. 5Publicly accessible sites are open to the general public and routinely accommodate pedestrians and include, but are not limited to, schools, churches, hospitals, parks, nature trails, businesses open to the public, and sidewalks. Temporary structures, public roads or similar thoroughfares are not considered publicly accessible. 6A closed sinkhole does not have an open conduit to groundwater. The setback from a closed sinkhole may be reduced or waived by the department upon evaluation by a professional soil scientist.

(2) In cases where more than one setback distance is involved, the most restrictive distance governs.

(3) Waivers. Waivers from adjacent property residents and landowners may only be used to reduce setback distances from occupied dwellings and property lines.

(4) Extended setback distances. The department may increase setback requirements based on site specific features, such as agricultural drainage features and site slopes.

f. Voluntary extensions of setback distances. If a permit holder negotiates a voluntary agreement with a landowner or resident to extend setback distances or add other more restrictive criteria than required by this regulation, the permit holder shall document the agreement in writing and provide the agreement to the department. Voluntary setback increases or other management criteria will not become an enforceable part of the land application permit unless the permit holder modifies the biosolids management plan to include the additional restriction.

g. Extension of setback distances with phosphorus index. If the application rate included in a nutrient management plan for a biosolids land application site is dependent upon an extended setback distance calculated using the phosphorus index, the phosphorus index calculations shall be included in the nutrient management plan. The extended setback distance shall be an enforceable part of the permit.

A. Conditions under which vector attraction reductions are required:

1. One of the vector attraction reduction requirements in subdivisions B 1 through B 10 of this section shall be met when bulk biosolids is applied to agricultural land, forest, a public contact site, or a reclamation site;

2. One of the vector attraction reduction requirements in subdivisions B 1 through B 8 of this section shall be met when bulk biosolids is applied to a lawn or a home garden;

3. One of the vector attraction reduction requirements in subdivisions B 1 through B 8 of this section shall be met when biosolids is sold or given away in a bag or other container for application to the land;

4. One of the vector attraction reduction requirements in subdivisions B 1 through B 11 of this section shall be met when sewage sludge (other than domestic septage) is placed on an active sewage sludge unit;

5. One of the vector attraction reduction requirements in subdivision B 9, B 10, or B 12 of this section shall be met when domestic septage is applied to agricultural land, forest, or a reclamation site; and

6. One of the vector attraction reduction requirements in subdivisions B 9 through B 12 shall be met when domestic septage is placed on an active sewage sludge unit.

B. Vector attraction reduction options:

1. The mass of volatile solids in the sewage sludge shall be reduced by a minimum of 38%, calculated according to the method in 9VAC25-32-450 F 8.

2. When the 38% volatile solids reduction requirement in subdivision 1 of this subsection cannot be met for an anaerobically digested sewage sludge, vector attraction reduction can be demonstrated by digesting a portion of the previously digested sewage sludge anaerobically in the laboratory in a bench-scale unit for 40 additional days at a temperature between 30°C and 37°C. When at the end of the 40 days, the volatile solids in the sewage sludge at the beginning of that period is reduced by less than 17%, vector attraction reduction is achieved.

3. When the 38% volatile solids reduction requirement in subdivision 1 of this section cannot be met for an aerobically digested sewage sludge, vector attraction reduction can be demonstrated by digesting a portion of the previously digested sewage sludge that has a percent solids of 2.0% or less aerobically in the laboratory in a bench-scale unit for 30 additional days at 20°C. When at the end of the 30 days, the volatile solids in the sewage sludge at the beginning of that period is reduced by less than 15%, vector attraction reduction is achieved.

4. The specific oxygen uptake rate (SOUR) for sewage sludge treated in an aerobic process shall be equal to or less than 1.5 milligrams of oxygen per hour per gram of total solids (dry weight basis) at a temperature of 20°C.

5. Sewage sludge shall be treated in an aerobic process for 14 days or longer. During that time, the temperature of the sewage sludge shall be higher than 40°C and the average temperature of the sewage sludge shall be higher than 45°C.

6. The pH of sewage sludge shall be raised to 12 or higher by alkaline addition and, without the addition of more alkaline material, shall remain at 12 or higher for two hours and then at 11.5 or higher for an additional 22 hours.

7. The percent solids of sewage sludge that does not contain unstabilized solids generated in a primary wastewater treatment process shall be equal to or greater than 75% based on the moisture content and total solids prior to mixing with other materials.

8. The percent solids of sewage sludge that contains unstabilized solids generated in a primary wastewater treatment process shall be equal to or greater than 90% based on the moisture content and total solids prior to mixing with other materials.

9. Sewage sludge injection requirements:

a. Sewage sludge shall be injected below the surface of the land.

b. No significant amount of the sewage sludge shall be present on the land surface within one hour after the sewage sludge is injected.

c. When the sewage sludge that is injected below the surface of the land is Class A with respect to pathogens, the sewage sludge shall be injected below the land surface within eight hours after being discharged from the pathogen treatment process.

10. Sewage sludge incorporation requirements:

a. Sewage sludge applied to the land surface or placed on an active sewage sludge unit shall be incorporated into the soil within six hours after application to or placement on the land unless otherwise specified by the board department.

b. When the sewage sludge that is incorporated into the soil is Class A with respect to pathogens, the sewage sludge shall be applied to or placed on the land within eight hours after being discharged from the pathogen treatment process.

11. Sewage sludge placed on an active sewage sludge unit shall be covered with soil or other material at the end of each operating day.

12. The pH of domestic septage shall be raised to 12 or higher by alkaline addition and, without the addition of more alkaline material, shall remain at 12 or higher for 30 minutes.
