TITLE 9. ENVIRONMENT

STATE WATER CONTROL BOARD

Chapter 720

Final Regulation

REGISTRAR'S NOTICE: The following regulatory action is exempt from the Administrative Process Act in accordance with § 2.2-4006 A 4 c of the Code of Virginia, which excludes regulations that are necessary to meet the requirements of federal law or regulations provided such regulations do not differ materially from those required by federal law or regulation. The State Water Control Board will receive, consider, and respond to petitions by any interested person at any time with respect to reconsideration or revision.

Title of Regulation: 9VAC25-720. Water Quality Management Planning Regulation (amending 9VAC25-720-50).

Statutory Authority: § 62.1-44.15 of the Code of Virginia; 33 USC § 1313(e) of the federal Clean Water Act.

Effective Date: November 23, 2011.

Agency Contact: John Kennedy, Department of Environmental Quality, 629 East Main Street, P.O. Box 10009, Richmond, VA 23240, telephone (804) 698-4312, or email john.kennedy@deq.virginia.gov.

Summary:

The regulation is amended to conform with the federal Environmental Protection Agency's Chesapeake Bay total maximum daily load (approved December 29, 2010); specifically, the total nitrogen waste load allocation (WLA) for the Fauquier County Water & Sewer Authority - Vint Hill WWTP (VPDES VA0020460). The amendment increases the total nitrogen WLA from 8,680 to 11,573 lbs/yr. In conjunction with this revision, the associated Footnote #8, which conditioned the nutrient WLAs on securing a certificate to operate for an expanded design flow by December 31, 2011, was deleted.

~~(9)~~ (8) Parkins Mill STP: waste load allocations (WLAs) based on a design flow capacity of 5.0 million gallons per day (MGD). If plant is not certified to operate at 5.0 MGD design flow capacity by December 31, 2010, the WLAs will decrease to TN = 36,547 lbs/yr; TP = 2,741 lbs/yr, based on a design flow capacity of 3.0 MGD.

~~(10)~~ (9) Merck-Stonewall – (a) these waste load allocations will be subject to further consideration, consistent with the Chesapeake Bay TMDL, as it may be amended, and possible reduction upon "full-scale" results showing the optimal treatment capability of the 4-stage Bardenpho technology at this facility consistent with the level of effort by other dischargers in the region. The "full scale" evaluation will be completed by December 31, 2011, and the results submitted to DEQ for review and subsequent board action; (b) in any year when credits are available after all other exchanges within the Shenandoah-Potomac River Basin are completed in accordance with § 62.1-44.19:18 of the Code of Virginia, Merck shall acquire credits for total nitrogen discharged in excess of 14,619 lbs/yr and total phosphorus discharged in excess of 1,096 lbs/yr; and (c) the allocations are not transferable and compliance credits are only generated if discharged loads are less than the loads identified in clause (b).

~~(11)~~ (10) Opequon WRF: (a) the TN WLA is derived based on 3 mg/l of TN and 12.6 MGD; (b) the TN WLA includes an additional allocation for TN in the amount of 6,729 lbs/yr by means of a landfill leachate consolidation and treatment project; and (c) the TP WLA is derived based on 0.3 mg/l of TP and 12.6 MGD.
