c. Upon the department's approval of the registration statement, a facility will be included in the registration list maintained by the department.

2. Authorization to discharge for facilities not required to register. Any facility authorized by a Virginia Pollutant Discharge Elimination System permit and not required by this general permit to submit a registration statement shall be deemed to be authorized to discharge total nitrogen and total phosphorus under this general permit at the time it is issued. Owners or operators of facilities that are deemed to be permitted under this subsection shall have no obligation under this general permit prior to submitting a registration statement and securing coverage under this general permit based upon such registration statement.

3. Continuation of permit coverage.

a. Any owner authorized to discharge under this general permit and who submits a complete registration statement for the reissued general permit by November 1, 2016, in accordance with Part III A or who is not required to register in accordance with Part I A 2 is authorized to continue to discharge under the terms of this general permit until such time as the board either:

(1) Issues coverage to the owner under the reissued general permit, or

(2) Notifies the owner that coverage under the reissued permit is denied.

b. When the owner that was covered under the expiring or expired general permit has violated or is violating the conditions of that permit, the board may choose to do any or all of the following:

(1) Initiate enforcement action based upon the general permit that has been continued,

(2) Issue a notice of intent to deny coverage under the amended general permit if the general permit coverage is denied the owner would then be required to cease the activities authorized by the continued general permit or be subject to enforcement action for operating without a permit, or

(3) Take other actions authorized by the State Water Control Law.

B. Waste load allocations.

1. Waste load allocations allocated to permitted facilities pursuant to 9VAC25-720-50 C, 9VAC25-720-60 C, 9VAC25-720-70 C, 9VAC25-720-110 C, and 9VAC25-720-120 C of the Water Quality Management Planning Regulation, or applicable total maximum daily loads, or waste load allocations acquired by new and expanding facilities to offset new or increased delivered total nitrogen and delivered total phosphorus loads from a new discharge or expansion under Part II B of this general permit, and existing loads calculated from the permitted design capacity of expanding facilities not previously covered by this general permit, shall be incorporated into the registration list maintained by the department. The waste load allocations contained in this list shall be enforceable as annual mass load limits in this general permit. Credits shall not be generated by facilities whose mass loads are derived from permitted design capacities, or from facilities whose operations were previously authorized by a Virginia Pollution Abatement (VPA) permit that was issued before July 1, 2005.

2. Except as described in subdivision subdivisions 2 d and 2 e of this subsection, an owner or operator of two or more facilities covered by this general permit and located in the same tributary may apply for and receive an aggregated mass load limit for delivered total nitrogen and an aggregated mass load limit for delivered total phosphorus reflecting the total of the water quality-based total nitrogen and total phosphorus waste load allocations or permitted design capacities established for such facilities individually.

a. The permittee (and all of the individual facilities covered under a single registration) shall be deemed to be in compliance when the aggregate mass load discharged by the facilities is less than the aggregate load limit.

b. The permittee will be eligible to generate credits only if the aggregate mass load discharged by the facilities is less than the total of the waste load allocations assigned to any of the affected facilities in 9VAC25-720-50 C, 9VAC25-720-60 C, 9VAC25-720-70 C, 9VAC25-720-110 C and 9VAC25-720-120 C of the Water Quality Management Planning Regulation.

c. Credits shall not be generated by permittees whose aggregated mass load limit is derived entirely from permitted design capacities.

d. The aggregation of mass load limits shall not affect any requirement to comply with local water quality-based limitations.

e. Facilities whose operations were previously authorized by a Virginia Pollution Abatement (VPA) permit that was issued before July 1, 2005, cannot be aggregated with other facilities under common ownership or operation.

f. Operation under an aggregated mass load limit in accordance with this section shall not be deemed credit acquisition as described in Part I J 2 of this general permit.

3. An owner who consolidates two or more facilities located in the same tributary into a single regional facility may apply for and receive an aggregated mass load limit for delivered total nitrogen and an aggregated mass load limit for delivered total phosphorus, subject to the following conditions:

a. If all of the affected facilities have waste load allocations in 9VAC25-720-50 C, 9VAC25-720-60 C, 9VAC25-720-70 C, 9VAC25-720-110 C, and 9VAC25-720-120 C of the Water Quality Management Planning Regulation, the aggregate mass load limit shall be calculated by adding the waste load allocations of the affected facilities. The regional facility shall be eligible to generate credits.

b. If any, but not all, of the affected facilities has a waste load allocation in 9VAC25-720-50 C, 9VAC25-720-60 C, 9VAC25-720-70 C, 9VAC25-720-110 C, and 9VAC25-720-120 C of the Water Quality Management Planning Regulation, the aggregate mass load limit shall be calculated by adding:

(1) Waste load allocations of those facilities that have wasteload waste load allocations in 9VAC25-720-50 C, 9VAC25-720-60 C, 9VAC25-720-70 C, 9VAC25-720-110 C, and 9VAC25-720-120 C of the Water Quality Management Planning Regulation;

(2) Permitted design capacities assigned to affected industrial facilities; and

(3) Loads from affected sewage treatment works that do not have a waste load allocation in 9VAC25-720-50 C, 9VAC25-720-60 C, 9VAC25-720-70 C, 9VAC25-720-110 C, and 9VAC25-720-120 C of the Water Quality Management Planning Regulation, defined as the lesser of a previously calculated permitted design capacity, or the values calculated by the following formulae:

Nitrogen Load (lbs/day) = flow (expressed as MGD to the nearest 0.01 MGD) x 8.0 mg/l x 8.3438 8.345 x 365 days/year

Phosphorus Load (lbs/day) = flow (expressed as MGD to the nearest 0.01 MGD) x 1.0 mg/l x 8.3438 8.345 x 365 days/year

Flows used in the preceding formulae shall be the design flow of the treatment works from which the affected facility currently discharges.

The regional facility shall be eligible to generate credits.

c. If none of the affected facilities have a waste load allocation in 9VAC25-720-50 C, 9VAC25-720-60 C, 9VAC25-720-70 C, 9VAC25-720-110 C, and 9VAC25-720-120 C of the Water Quality Management Planning Regulation, the aggregate mass load limit shall be calculated by adding the respective permitted design capacities for the affected facilities. The regional facility shall not be eligible to generate credits.

d. Facilities whose operations were previously authorized by a Virginia Pollution Abatement (VPA) permit that was issued before July 1, 2005, may be consolidated with other facilities under common ownership or operation, but their allocations cannot be transferred to the regional facility.

e. Facilities whose operations were previously authorized by a VPA permit that was issued before July 1, 2005, can become regional facilities, but they cannot receive additional allocations beyond those permitted in Part II B 1 d of this general permit.

4. Unless otherwise noted, the nitrogen and phosphorus waste load allocations assigned to permitted facilities are considered total loads including nutrients present in the intake water from the river, as applicable. On a case-by-case basis, an industrial discharger may demonstrate to the satisfaction of the board that a portion of the nutrient load originates in its intake water. This demonstration shall be consistent with the assumptions and methods used to derive the allocations through the Chesapeake Bay models. In these cases, the board may limit the permitted discharge to the net nutrient load portion of the assigned waste load allocation.

5. Bioavailability. Unless otherwise noted, the entire nitrogen and phosphorus waste load allocations assigned to permitted facilities are considered to be bioavailable to organisms in the receiving stream. On a case-by-case basis, a discharger may demonstrate to the satisfaction of the board that a portion of the nutrient load is not bioavailable; this demonstration shall not be based on the ability of the nutrient to resist degradation at the wastewater treatment plant, but instead, on the ability of the nutrient to resist degradation within a natural environment for the amount of time that it is expected to remain in the bay watershed. This demonstration shall also be consistent with the assumptions and methods used to derive the allocations through the Chesapeake Bay models. In these cases, the board may limit the permitted discharge to the bioavailable portion of the assigned waste load allocation.

C. Schedule of compliance.

1. The following schedule of compliance pertaining to the load allocations for total nitrogen and total phosphorus applies to the facilities listed in each tributary, as listed 9VAC25-820-80.

a. Compliance shall be achieved as soon as possible, but no later than the following dates, subject to any compliance plan-based adjustment by the board pursuant to subdivision 1 b of this subsection, for each parameter:

b. Following submission of compliance plans and compliance plan updates required by 9VAC25-820-40, the board shall reevaluate the schedule of compliance in subdivision 1 a of this subsection, taking into account the information in the compliance plans and the factors in § 62.1-44.19:14 C 2 of the Code of Virginia. When warranted based on such information and factors, the board shall adjust the schedule in subdivision 1 a of this subsection as appropriate by modification or reissuance of this general permit.

2. The registration list shall contain individual dates for compliance (as defined in Part I J 1 a-b of this general permit) for dischargers, as follows:

a. Facilities that were required to submit a registration statement with the department by January 1, 2007, listed in 9VAC25-820-80 will have individual dates for compliance based on their respective compliance plans, that may be earlier than the basin schedule listed in subdivision 1 of this subsection.

b. Facilities listed in 9VAC25-820-70 that have waived waive their compliance schedules in accordance with 9VAC25-820-40 A 2 b shall have an individual compliance date of January 1, 2007 2012.

c. Upon completion of the projects contained in their compliance plans, facilities listed in 9VAC25-820-80 may receive a revised individual compliance date of January 1 for the calendar year immediately following the year in which a Certificate to Operate was issued for the capital projects, but not later than the basin schedule listed in subdivision 1 of this subsection.

d. New and expanded facilities will have individual dates for compliance corresponding to the date that coverage under this general permit was extended to the facility.

3. The 39 significant dischargers in the James River Basin shall meet aggregate [ delivered discharged ] waste load allocations of8,163,209 8,968,864 ] lbs/yr TN and457,384 545,558 ] lbs/yr TP by January 1, 2023.

D. Annual update of compliance plan. Every owner or operator of a facility required to submit a registration statement shall either individually or through the Virginia Nutrient Credit Exchange Association submit updated compliance plans to the department no later than February 1 of each year. The compliance plans shall contain [ , at a minimum, any capital projects and implementation schedules needed to achieve sufficient information to document a plan for the facility to achieve and maintain compliance with applicable ] total nitrogen and phosphorus [ reductions sufficient to comply with the ] individual waste load allocations on the registration list and combined aggregate waste load allocations of all the permittees in the tributary Part I C 3. Compliance plans for facilities that were required to submit a registration statement with the department by January 1, 2007, under Part I G 1 a may rely on the acquisition of point source credits in accordance with Part I J of this general permit, but not the acquisition of credits through payments into the Water Quality Improvement Fund, to achieve compliance with the individual and combined waste load allocations in each tributary. Compliance plans for expansions or new discharges for facilities that are required to submit a registration statement with the department under Part I G 1 b and c may rely on the acquisition of allocation in accordance with Part II B of this general permit to achieve compliance with the individual and combined waste load allocations in each tributary.

E. Monitoring requirements.

1. Discharges shall be monitored by the permittee during weekdays as specified below unless the department determines that weekday only sampling results in a non-representative load. Weekend monitoring and/or alternative monthly load calculations to address production schedules or seasonal flows shall be submitted to the department for review and approval on a case-by-case basis:. Facilities that exhibit instantaneous discharge flows that vary from the daily average discharge flow by less than 10% may submit a proposal to the department to use an alternative sample type; such proposals shall be reviewed and approved by the department on a case-by-case basis. ]

2. Monitoring for compliance with effluent limitations shall be performed in a manner identical to that used to determine compliance with effluent limitations established in the individual VPDES permit and monitoring. Monitoring or sampling shall be conducted according to analytical laboratory methods approved under 40 CFR Part 136 (2006), unless other test or sample collection procedures have been requested by the permittee and approved by the department in writing. All analysis for compliance with effluent limitations shall be in accordance with 1VAC30-45, Certification for Noncommercial Environmental Laboratories, or 1VAC30-46, Accreditation for Commercial Environmental Laboratories. Monitoring may be performed by the permittee at frequencies more stringent than listed above; however, the permittee shall report all results of such monitoring.

3. Loading values greater than or equal to 10 pounds reported in accordance with Part I E and F of this general permit shall be calculated and reported to the nearest pound without regard to mathematical rules of precision. Loading values of less than 10 pounds reported in accordance with Part I E and F of this general permit shall be calculated and reported to at least two significant digits with the exception that all complete calendar year annual loads shall be reported to the nearest pound.

4. Data shall be reported on a form provided by the department, by the same date each month as is required by the facility's individual permit. The total monthly load shall be calculated in accordance with the following formula:

ML = MLavg * d

where:

ML = total monthly load (lb/mo)

MLavg = monthly average load as reported on DMR (lb/d)

d = number of discharge days in the calendar month

MLavg = http://leg5.state.va.us/images/421655679733LEGLDH_files/image001.gif

http://leg5.state.va.us/images/490444572632DEQGC_files/image001.gif

where:

ML = total monthly load (lb/mo) = average daily load for the calendar month multiplied by the number of days of the calendar monthon which a discharge occurred ]

DL = daily load = daily concentration (expressed as mg/l to the nearest 0.01 mg/l) multiplied by the flow volume of effluent discharged during the 24-hour period (expressed as MGD to at least the nearest 0.01 MGD) MGD and in no case less than two significant digits), multiplied by 8.3438 and 8.345. Daily loads greater than or equal to 10 pounds may be rounded to the nearest whole number to convert to pounds per day (lbs/day). Daily loads less than or equal to 10 pounds may be rounded to no fewer than two significant fiqures.

s = number of days in the calendar month in which a sample was collected and analyzed

d = number of discharge days in the calendar month

All For total phosphorus, all daily concentration data below the quantification level (QL) for the analytical method used should be treated as half the QL. All daily concentration data equal to or above the QL for the analytical method used shall be treated as it is reported. If all data are below the QL, then the average shall be reported as half the QL.

For total nitrogen (TN), if none of the daily concentration data for the respective species (i.e., TKN, nitrates/nitrites) are equal to or above the QL for the respective analytical methods used, the daily TN concentration value reported shall equal one half of the largest QL used for the respective species. If one of the data is equal to or above the QL, the daily TN concentration value shall be treated as that data point as reported. If more than one of the data is above the QL, the daily TN concentration value shall equal the sum of the data points as reported.

The total year-to-date mass load shall be calculated in accordance with the following formula:

AL-YTD = http://leg5.state.va.us/images/421655679733LEGLDH_files/image002.gif

http://leg5.state.va.us/images/490509944083DEQGC_files/image001.gif

where:

AL-YTD = calendar year-to-date annual load (lb/yr)

ML = total monthly load (lb/mo) as reported on DMR

5. The department may authorize a chemical usage evaluation as an alternative means of determining nutrient loading for outfalls where the only source of nutrients is those found in the surface water intake and chemical additives used by the facility. Such an evaluation shall be submitted to the department for review and approval on a case-by-case basis. Implementation of approved chemical usage evaluations shall satisfy the requirements specified under Part I E 1 and 2. ]

F. Annual reporting.

1. Annually, on or before February 1, the permittee shall either individually or through the Virginia Nutrient Credit Exchange Association file a report with the department, using a reporting form supplied by the department. The report shall identify:

a. The annual mass load of total nitrogen and the annual mass load of total phosphorus discharged by each of its permitted facilities during the previous calendar year;

b. The delivered total nitrogen load and delivered total phosphorus load discharged by each of its permitted facilities during the previous year; and

c. The number of total nitrogen and total phosphorus credits for the previous calendar year to be acquired or eligible for exchange by the permittee.

The total annual mass load shall be calculated in accordance with the following formula:

AL = http://leg5.state.va.us/images/421655679733LEGLDH_files/image003.gif

http://leg5.state.va.us/images/490510092403DEQGC_files/image001.gif

where:

AL = calendar year annual load (lb/yr)

ML = total monthly load (lb/mo) as reported on DMR

a. Bypass is prohibited, and the board may take enforcement action against a permittee for bypass, unless:

(1) Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage;

(2) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass that occurred during normal periods of equipment downtime or preventive maintenance; and

(3) The permittee submitted notices as required under subdivision 2 of this subsection.

b. The board may approve an anticipated bypass, after considering its adverse effects, if the board determines that it will meet the three conditions listed above in subdivision 3 a of this subsection.

N. Upset.

1. An upset constitutes an affirmative defense to an action brought for noncompliance with such technology-based permit effluent limitations if the requirements of subdivision 2 of this subsection are met. No determination made during administrative review of claims that noncompliance was caused by upset, and before an action for noncompliance, is final administrative action subject to judicial review.

2. A permittee who wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that:

a. An upset occurred and that the permittee can identify the cause(s) of the upset;

b. The permitted facility was at the time being properly operated;

c. The permittee submitted notice of the upset as required in subdivision L 7 b (2) of this section (24-hour notice); and

d. The permittee complied with any remedial measures required under subsection D of this section.

3. In any enforcement proceeding, the permittee seeking to establish the occurrence of an upset has the burden of proof.
