REGULATIONS

Vol. 27 Iss. 12 - February 14, 2011

TITLE 9. ENVIRONMENT

VIRGINIA WASTE MANAGEMENT BOARD

Chapter 260

Proposed Regulation

Title of Regulation: 9VAC25-260. Water Quality Standards (amending 9VAC25-260-450).

Statutory Authority: § 62.1-44.15 of the Code of Virginia; 33 USC § 1251 et seq.; 40 CFR Part 131.

Public Hearing Information: No public hearings are scheduled.

Public Comment Deadline: April 15, 2011.

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

Basis: Section 62.1-44.15 of the Code of Virginia mandates and authorizes the board to establish water quality standards and policies for any state waters consistent with the purpose and general policy of the State Water Control Law and to modify, amend, or cancel any such standards or policies established. The federal Clean Water Act at § 303(c) mandates the State Water Control Board to review and, as appropriate, modify and adopt water quality standards. The corresponding federal water quality standards regulation at 40 CFR 131.6 describes the minimum requirements for water quality standards. The minimum requirements are use designations, water quality criteria to protect the designated uses, and an antidegradation policy.

The proposed amendments do not exceed the minimum requirements of any legally binding state or federal mandates, nor are they more stringent than federal requirements, which require, as a minimum, that states have a process whereby states may designate the uses for a water body. The U.S. Environmental Protection Agency (EPA) Water Quality Standards regulation (40 CFR 131.10) is the regulatory basis for the EPA requiring the states to specify designated uses. EPA retains approval/disapproval oversight, but delegates to the states the election and designation of specific public water supplies.

Purpose: The proposed amendments to the regulation are necessary to protect the health, safety, or welfare of citizens by providing appropriate water quality protection for a downstream public water supply. Although the majority of the water supply users would be citizens of North Carolina, the water supply (Dan River) is shared by Virginia and North Carolina. Federal regulation (40 CFR 131.10(b)) states "...the State shall take into consideration the water quality standards of downstream waters and shall ensure that its water quality standards provide for the attainment and maintenance of the water quality standards of downstream waters." North Carolina water quality standards require public water supply protection for a 10-mile distance upriver from a drinking water supply intake that includes tributaries as well as the river main stem. The Dan River and some of its tributaries exit North Carolina and enter Virginia before this 10-mile limit from the North Carolina proposed intake is reached.

Substance: The proposed amendment adds a public water supply (PWS) notation in the special standards column of 9VAC25-260-450 and associated narrative language describing that portion of the Dan River and tributaries to which the PWS special standard applies.

Issues: The primary advantage to the public is providing appropriate water quality protection to a public drinking water supply source. The primary disadvantage is that PWS criteria listed in the parameter table of 9VAC25-260-140 B apply to waters designated as PWS and may lead to more stringent effluent limits for affected dischargers. There are two permitted facilities within the proposed PWS segment. One is an individual permit with several stormwater discharges and the other is a Stormwater Industrial General Permit. Agency water permits staff is not aware of any impacts the designation would have on these facilities. The City of Danville North Side waste water treatment facility discharge point (with a diffuser) to the Dan River is a little over one-tenth of a mile upstream of the terminus of the proposed PWS segment. Low flow conditions are utilized at the point of discharge when permit limits are calculated. A downstream water withdrawal would not affect calculation of permit limits for Danville's discharge.

This regulatory action poses 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 to amend the Water Quality Standards, Section 9VAC25-260-450, by designating as Public Water Supply (9VAC25-260-380 D 1) an approximately one mile segment of the Dan River in Virginia and its tributaries in Virginia near the North Carolina border.

Result of Analysis. There is insufficient data to accurately compare the magnitude of the benefits versus the costs.

Estimated Economic Impact. A raw water intake intended to serve Roxboro, North Carolina, and the North Carolina counties of Person and Caswell has been proposed by the state of North Carolina for the Dan River near the town of Milton, North Carolina, approximately 10 miles downriver from Danville, Virginia. North Carolina water quality standards require public water supply protections to extend 10 miles upriver from the intake. The Board received a petition to designate as public water supply (PWS) a sufficient portion of the Dan River and its tributaries to complete the 10-mile run of the river as required by North Carolina water quality standards. In order to comply with North Carolinas request, the Board proposes to designate approximately a one mile segment of the Dan River in Virginia and its tributaries in Virginia near the state line as PWS.

Waters designated as PWS have more stringent effluent limits for affected dischargers. According to the Department of Environmental Quality (Department) there are two permitted facilities within the proposed PWS segment. One has an individual permit with several stormwater discharges (Goodyear) and the other has a stormwater industrial general permit (Blue Ridge Fiberboard). The Department does not believe that the more stringent effluent limits for waters designated PWS will affect these two firms given their current type and level of discharge. Thus the proposed amendment does not produce an immediate cost. There is some potential future cost in that designating the segment as PWS would make some potential industrial uses (for firms who may consider locating within the segment in question) more expensive with the more stringent PWS discharge standards.

On the other hand, federal regulation (40 CFR 131.10(b)) states "...the State shall take into consideration the water quality standards of downstream waters and shall ensure that its water quality standards provide for the attainment and maintenance of the water quality standards of downstream waters." Though the benefit for public drinking water quality by designating the segment as PWS would be for North Carolina in this case, complying with North Carolinas request will likely generate goodwill and may increase the likelihood that North Carolina will comply with potential future requests from Virginia.

Since it is unknown whether any firms would in practice wish to exceed the more stringent PWS discharge standards in the future, and the amount of goodwill and the likely benefit of such goodwill cannot be easily quantified, there is insufficient information to conclusively determine whether or not the costs of the proposed amendment exceed the benefits.

Businesses and Entities Affected. Currently there are two permitted facilities within the proposed PWS designation: Goodyear-Danville on Hogans Creek, which is a tributary to the Dan River, and Blue Ridge Fiberboard on the Dan River. Blue Ridge Fiberboard is a small business while Goodyear is not. These two firms and any other potential firms that may wish to locate within the proposed PWS designated area are potentially affected by the proposed amendment.

Localities Particularly Affected. The proposed amendment particularly affects Pittsylvania County and the City of Danville.

Projected Impact on Employment. The proposal amendment is unlikely to significantly affect employment, at least in the near term.

Effects on the Use and Value of Private Property. The proposed amendments are unlikely to significantly affect current use of private property. Some potential industrial uses (for firms who may consider locating within the segment in question) would be more costly with the more stringent PWS discharge standards. This could potentially discourage some development on the approximately one mile segment of the Dan River in Virginia and its tributaries.

Small Businesses: Costs and Other Effects. The proposed amendments are unlikely to significantly affect small businesses currently located within the segment. Some potential industrial uses (for firms who may consider locating within the segment in question) would be more costly with the more stringent PWS discharge standards.

Small Businesses: Alternative Method that Minimizes Adverse Impact. Other than denying North Carolinas request to designate the segment as PWS, there is no alternative method that would reduce adverse impact.

Real Estate Development Costs. Designating the approximately one mile segment of the Dan River in Virginia and its tributaries as PWS could increase the costs of development on the segment if the potential development involved discharge in excess of the PWS criteria. This could potentially discourage some development on the approximately one mile segment of the Dan River in Virginia and its tributaries.

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, 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 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 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 proposed amendments designate an approximately one-mile segment of the Dan River in Virginia and its tributaries in Virginia near the Virginia/North Carolina state line as public water supply. A raw water intake intended to serve Roxboro, North Carolina, and the North Carolina counties of Person and Caswell is proposed by the state of North Carolina for the Dan River near the town of Milton, North Carolina, approximately 10 miles downriver from Danville, Virginia. North Carolina water quality standards require public water supply protections to extend 10 miles upriver from the intake. The State Water Control Board received a petition to designate as public water supply a sufficient portion of the Dan River and its tributaries to complete the 10-mile run of the river as required by North Carolina water quality standards.
