Fast-Track Regulation

Title of Regulation: 9VAC25-720. Water Quality Management Planning Regulation (amending 9VAC25-720-50, 9VAC25-720-60, 9VAC25-720-70, 9VAC25-720-110, 9VAC25-720-120).

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

Public Hearing Information: No public hearings are scheduled.

Public Comment Deadline: July 15, 2015.

Effective Date: July 30, 2015.

Agency Contact: John Kennedy, Department of Environmental Quality, 629 East Main Street, P.O. Box 1105, Richmond, VA 23218, telephone [phone], FAX [phone], or email [e-mail].

Basis: Section 62.1-44.15 of the Code of Virginia authorizes the State Water Control Board to promulgate these amendments. The scope and purpose of the State Water Control Law is to protect and to restore the quality of state waters, to safeguard the clean waters from pollution, to prevent and to reduce pollution and to promote water conservation. Subdivision 10 of § 62.1-44.15 of the Code of Virginia mandates the board to adopt such regulations as it deems necessary to enforce the general water quality management program of the board in all or part of the Commonwealth. In addition, subdivision 14 of § 62.1-44.15 of the Code of Virginia requires the board to establish requirements for the treatment of sewage, industrial wastes, and other wastes that are consistent with the purposes of State Water Control Law (Chapter 3.1 of Title 62.1 of the Code of Virginia). The specific effluent limits needed to meet the water quality goals are discretionary. The correlation between the proposed regulatory action and the legal authority identified in this basis statement is that the amendments being considered are modifications of the current requirements for the treatment of wastewater that will contribute to the attainment of the Virginia water quality standards.

Purpose: The purpose of this rulemaking is to protect state waters by adopting regulations that are technically correct, necessary, and reasonable. Nutrients discharged from wastewater treatment plants contribute to the overall loading of nutrients to the Chesapeake Bay and its tributaries. These nutrients have been identified as pollutants causing adverse impacts on large portions of the Bay and its tidal rivers, which are included in the list of impaired waters required under § 303(d) of the Clean Water Act and § 62.1-44.19:5 of the Code of Virginia. Waters not meeting standards require development of a total maximum daily load (TMDL), also mandated under the same sections of federal and state law. The federal Environmental Protection Agency (EPA) adopted the Chesapeake Bay TMDL in December 2010, and Virginia is now following a watershed implementation plan to meet the requirements of that TMDL, in part by setting regulatory nutrient wasteload allocations (WLAs).

The amendments that are the subject of this rulemaking are part of the regulatory framework that governs the discharge of total nitrogen and total phosphorus for certain wastewater facilities within Virginia's portion of the Chesapeake Bay watershed. Resulting permit limitations are expressed principally as annual wasteload allocations, and also as technology-based annual average concentrations where appropriate and authorized. The proposed amendments are needed to make the Water Quality Management Program (WQMP) Regulation current by:

1. Deleting obsolete footnotes and, where appropriate, maintaining basin total WLAs by placing WLA balances resulting from self-enacting footnotes into an unallocated reserve,

2. Making revisions to nutrient WLAs resulting from appeals and settlements under the WQMP Regulation, adoption of EPA's Chesapeake Bay TMDL, and reissuance in 2012 of the Chesapeake Bay Nutrient Discharge Watershed General Permit (9VAC25-820),

3. Making technical corrections to facility names or permit numbers, and

4. Making expression of WLAs consistent for all facilities served by combined sewer systems.

The scope and purpose of the State Water Control Law is to protect and to restore the quality of state waters, safeguard the clean waters from pollution, prevent and reduce pollution, and promote water conservation.

Rationale for Using Fast-track Process: In late 2005 the State Water Control Board adopted amendments to the WQMP Regulation that set annual total nitrogen (TN) and total phosphorus (TP) wasteload allocations (WLAs) for significant dischargers in the Chesapeake Bay watershed. Included in those amendments were numerous footnotes establishing a deadline for certain facilities to secure a certificate to operate for expanded design capacity, upon which their WLAs would be based if the deadline was met.

Due to passing of the deadline for "footnoted" facilities, as well as several appeals and settlements under the WQMP Regulation, adoption of EPA's Chesapeake Bay TMDL (December 2010), and reissuance in 2012 of the Chesapeake Bay Nutrient Discharge Watershed General Permit (9VAC25-820), there are several significant dischargers that must have their WLAs amended in this chapter. These revisions are expected to be noncontroversial due to the self-enacting nature of the footnotes, and the revisions are exempt actions (TMDL-related) under the Administrative Process Act necessary to meet the requirements of federal law. Another revision affecting the Alexandria Sanitation Authority facility (d.b.a. Alexandria Renew Enterprises) will make expression of their WLAs consistent with two other facilities that also have combined sewer systems, and whose WLAs were adopted without opposition in 2005.

Substance: The amendments:

1. Delete obsolete footnotes and, where appropriate, maintain basin total WLAs by placing WLA balances resulting from self-enacting footnotes into an unallocated reserve.

2. Revise TN and TP WLAs for several facilities as the result of:

a. Water Quality Management Program Regulation appeals and settlements.

b. EPA adoption of the Chesapeake Bay TMDL. These are exempt actions (TMDL-related) under § 2.2-4006 A 4 c of the Administrative Process Act (Necessary to meet the requirements of federal law).

3. Make expression of WLAs consistent for all facilities served by combined sewer systems.

4. Make technical housekeeping revisions (e.g., changes to facility name, consolidation of dischargers into a regional system, and revision of discharge permit numbers).

Issues: The public will benefit because these amendments will result in updating and correcting the Water Quality Management Planning Regulation, which is part of Virginia's plan to control the discharge of nitrogen and phosphorus from wastewater treatment plants in the Chesapeake Bay watershed. This, in turn, will aid in the restoration of water quality in the Chesapeake Bay and its tributary rivers and assist in meeting the water quality standards necessary for protection of the living resources that inhabit the Bay, as mandated by the EPA Chesapeake Bay Total Maximum Daily Load. There are no disadvantages to the public or the Commonwealth.

Department of Planning and Budget's Economic Impact Analysis:

Summary of the Proposed Amendments to Regulation. The State Water Control Board (Board) proposes the following amendments to the Water Quality Management Planning Regulation: 1) delete obsolete footnotes and, where appropriate, maintain basin total waste load allocations by placing waste load allocation (WLA) balances resulting from self-enacting footnotes into an unallocated reserve, 2) make revisions to nutrient WLAs resulting from appeals and settlements under this regulation, adoption of Environmental Protection Agencys Chesapeake Bay total maximum daily load, and reissuance in 2012 of the Chesapeake Bay Nutrient Discharge Watershed General Permit (9VAC25-820), 3) make technical corrections to facility names or permit numbers, and 4) make expression of WLAs consistent for all facilities served by combined sewer systems.

Result of Analysis. The benefits likely exceed the costs for all proposed changes.

Estimated Economic Impact. All proposed changes do one or more of the following: eliminate obsolete language, clarify existing requirements, or conform requirements to existing federal requirements which must already be followed by the regulated entities. Thus the proposed amendments are beneficial in that they should provide greater clarity, but otherwise should not have a significant impact.

Businesses and Entities Affected. The proposed amendments affect 26 publicly and privately owned wastewater treatment facilities.

Localities Particularly Affected. The proposed amendments affect publicly and privately owned wastewater treatment facilities in the following localities: 1) Cities of Alexandria, Harrisonburg, and Winchester, 2) Counties of Caroline, Chesterfield, Culpeper, Fauquier, Frederick, Hanover, King George, King William, Loudoun, Mathews, New Kent, Prince William, Rockingham, Shenandoah, Spotsylvania, and York, and 3) Towns of Broadway, Cape Charles, Culpeper, Gordonsville, Leesburg, Mount Jackson, New Market, Onancock, Purcellville, and West Point.

Projected Impact on Employment. The proposed amendments will not likely have a large impact on employment.

Effects on the Use and Value of Private Property. The proposed amendments will not likely have a large impact on the use and value of private property.

Small Businesses: Costs and Other Effects. The proposed amendments will not likely significantly affect small business costs.

Small Businesses: Alternative Method that Minimizes Adverse Impact. The proposed amendments do not adversely affect small businesses.

Real Estate Development Costs. The proposed amendments will not likely significantly affect real estate development costs.

Legal Mandate. The Department of Planning and Budget (DPB) has analyzed the economic impact of this proposed regulation in accordance with § 2.2-4007.04 of the Administrative Process Act and Executive Order Number 14 (10). Section 2.2-4007.04 requires that such economic impact analyses include, but need not be limited to, a determination of the public benefit, the projected number of businesses or other entities to whom the regulation would apply, the identity of any localities and types of businesses or other entities particularly affected, the projected number of persons and employment positions to be affected, the projected costs to affected businesses or entities to implement or comply with the regulation, and the impact on the use and value of private property. Further, if the proposed regulation has an adverse effect on small businesses, § 2.2-4007.04 requires that such economic impact analyses include (i) an identification and estimate of the number of small businesses subject to the regulation; (ii) the projected reporting, recordkeeping, and other administrative costs required for small businesses to comply with the regulation, including the type of professional skills necessary for preparing required reports and other documents; (iii) a statement of the probable effect of the regulation on affected small businesses; and (iv) a description of any less intrusive or less costly alternative methods of achieving the purpose of the regulation. The analysis presented above represents DPB's best estimate of these economic impacts.

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

Summary:

The amendments (i) delete obsolete footnotes and, where appropriate, maintain basin total wasteload allocations (WLA) by placing WLA balances resulting from self-enacting footnotes into an unallocated reserve; (ii) revise nutrient WLAs resulting from (a) appeals and settlements under this regulation, (b) adoption of Environmental Protection Agency's Chesapeake Bay total maximum daily load, and (c) reissuance in 2012 of the Chesapeake Bay Nutrient Discharge Watershed General Permit (9VAC25-820); (iii) make technical corrections to facility names or permit numbers; and (iv) make expression of WLAs consistent for all facilities served by combined sewer systems.
