a. The permittee shall report any noncompliance which that may adversely affect state waters or may endanger public health. An oral report must be provided to the department as soon as possible, but in no case later than 24 hours from the time the permittee becomes aware of the circumstances. A written report shall be submitted within five days and shall contain a description of the noncompliance and its cause; the period of noncompliance including exact dates and times, and, if the noncompliance has not been corrected, how long it is expected to continue, steps planned or taken to reduce, eliminate, and prevent a recurrence of the noncompliance. The board may waive the written report requirements on a case-by-case basis if the oral report has been received within 24 hours and no adverse impact on state waters has been reported. All other noncompliance reports which may not adversely affect state waters shall be submitted with the monitoring report. Reports shall include overflows.

b. The following shall be included as information which must be reported within 24 hours under this subdivision:

(1) Any unanticipated bypass; and

(2) Any upset which causes a discharge to surface waters.

J. Bypass.

1. A bypass of the treatment works is prohibited except as provided herein.

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 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.

9VAC25-32-450. Sampling, analysis, and preservation.

A. Representative samples of biosolids that is applied to the land or placed on a surface disposal site shall be collected and analyzed.

1. Raw sewage or sludge samples are to be collected prior to the treatment process unit operations.

2. Final treated samples are to be taken at a point following appropriate unit operations in the treatment process. An evaluation of biosolids treatment may require monitoring of fecal coliform levels in treated biosolids.

3. Composite samples shall be collected in accordance with the treatment works operation and maintenance manual.

B. Liquid biosolids. In the case of digesters and liquid storage holding tanks, a representative sample shall be composed of at least four grab samples obtained during daily operations at the facility or land application site. Samples of liquid biosolids obtained under pressure or vacuum should be obtained shortly after the beginning, during and at the end of the time period that the biosolids are produced at the sampling point.

C. Biosolids storage facilities. Equal volumes of biosolids shall be withdrawn from random locations across the width and throughout the length of the storage facility at the surface, mid-depth and near the bottom of the lagoon at each grab sample location. These grab samples shall be added to form a composite mix. A range of the minimum number of grab samples that should be obtained from various sizes of biosolids storage facilities in order to obtain a representative composite sample is presented in Table 1 of this section:

TABLE 1 MINIMUM NUMBER OF GRAB SAMPLES FROM STORAGE FACILITIES
Surface Area (Acres)	Minimum Number of Grab Samples
	Depth less than 4 feet	Depth greater than 4 feet
1 to 9.99	4 to 5	6 to 8
10 or more	6 to 8	9 to 11

D. Dewatered biosolids. Small, equally sized grab samples of the dewatered sludge stream may be taken at equally spaced intervals over the period of operation of the dewatering unit. Centrifuged biosolids samples may be taken from a belt conveyor or receiving hopper. Filter cake biosolids samples may be taken from a belt conveyor or a portion of the cake may be removed as it leaves the unit. The smaller grab samples should be combined to form a representative composite sample. A composite sample can be obtained over the daily operational period at the land application site.

E. Compost sampling. Collect composite samples composed of at least three grab samples of 1 one kilogram or more so that a representative average level of compost characteristics can be obtained from analytical testing. This mixture should be used for analytical testing or for combination with other composites to obtain a total composite sample representing a fixed period of operation. Compost samples may be taken with a scoop or shovel and placed in flexible bags that can be thoroughly shaken to mix grab samples.

F. Biosolids samples shall be preserved and analyzed in accordance with methods listed in 40 CFR Part 136 (2007) and methods identified in 9VAC25-31-490. Calculation procedures in the methods shall be used to calculate the percent volatile solids reduction for biosolids.

3. Permits may be modified or revoked upon the request of the permittee, or upon board initiative, to reflect the requirements of any changes in the statutes or regulations.

9VAC25-790-210. Nonconventional methods, processes or equipment.

A. Policy. The policy of the department is to encourage the development of any new or nonconventional methods, processes, and equipment that appear to have application for the treatment or conveyance of sewage. Sewage treatment methods, processes, and equipment may be subject to a special permit application procedure if (i) they are not covered by the Manual of Practice (Part III (9VAC25-790-310 et seq.) of this chapter) and (ii) they are in principle, or application, deemed to be nonconventional.

B. Provisional CTO. The performance reliability of nonconventional processes and equipment shall have been thoroughly demonstrated through an approved testing program for similar installations (loadings of 75% or more of design level) before they may be considered for conventional approval and use. Where the department approves such a testing program, a provisional CTO will be issued for treatment works in which new or nonconventional processes and equipment are to be evaluated. The provisional CTO will specify conditions related to the testing requirements and agreements necessary for issuance of a final CTO. The owner of the facility shall submit the required test results to the department according to an approved schedule for approval prior to issuance of a final CTO. It is the owner's responsibility to operate in compliance with requirements imposed by permits issued for the sewerage system or treatment works.

C. Assurance resources. As a prerequisite to the issuance of a provisional CTO, the owner must furnish assurance of financial ability or resources available to modify, convert, or replace, the new or nonconventional processes or equipment in the event the performance reliability cannot be established over the period of time specified by the provisional CTO. These assurances may be in the form of funds placed in escrow, letters of credit, performance bonds, etc., which would revert to the facility owner if performance reliability cannot be established.

D. Performance reliability testing. All procedures used in testing of the performance reliability shall be conducted under the supervision of a licensed professional engineer who shall attest to the accuracy of sampling and testing procedures. The required samples shall be tested through a qualified laboratory. The testing program shall provide as a minimum the following:

1. Samples shall be collected at designated locations at a stated frequency and analyzed in accordance with provisions of the provisional CTO. The minimum testing period shall be 12 months under the comparable environmental and operational conditions for which the process and equipment will receive conventional approvals for any additional installations.

2. All analyses shall be made in accordance with the 19th Edition of Standard Methods for the Examination of Water and Wastewater (1995) and 40 CFR Part 136 (July 1, 2003) as published in the 40 CFR July 1, 2017, update and 82 FR 40836 (August 28, 2017), or other approved analytical methods.

E. CTC. After the area engineer evaluates the plans and testing data, the director can issue a CTC if the performance data verifies that the method, process, or equipment can perform reliably in accordance with the design specifications and the operation standards of Part II, and that the method, process, or equipment may be installed as conventional for similar site specific operation.

F. Provisional CTO. Upon completion of construction or modification, a provisional CTO for a definite period of time will be issued for the operation of the nonconventional methods, processes, and equipment. Not more than one provisional CTO will be granted for a similar installation during the evaluation period. The provisional CTO shall require that:

1. The evaluation period shall be a minimum of 12 months and no longer than 18 months,

2. The holder of a provisional CTO must submit reports on operation during the evaluation period. The reports shall be prepared by either a licensed professional engineer experienced in the field of environmental engineering, the owner's operating or engineering staff, or a qualified testing firm.

G. Final CTO. The director will issue a final CTO upon lapse of the provisional CTO, if, on the basis of testing during that period, the new or nonconventional method, process, or equipment demonstrates reliable performance in accordance with permit requirements and the operation standards of Part II. If the standards are not met, then the owner shall provide for modification of the sewerage systems or treatment works, in a manner that will enable those standards to be met in accordance with this chapter.

9VAC25-870-15. Applicability of incorporated references based on the dates that they became effective.
