| Purpose of the meeting The DEQ will be holding a public meeting on the proposed modification to the Water Quality Management Planning Regulation, 9VAC25-720 for proposed amendments to Roanoke River Basin non-TMDL waste load allocation. In the case of inclement weather, the alternate date for the public meeting will be Wednesday, May 24, 2017 at 10am. The State Water Control Board (Board) seeks written and oral comments from interested persons on proposed amendments to the Water Quality Management Planning Regulation (WQMP) for the Roanoke River Basin non-TMDL waste load allocation. The Board is seeking public comment through the Department of Environmental Quality (DEQ). State mandate in the Code of Virginia §62.1-44.15, is the source of legal authority identified to promulgate this modification. The promulgating entity is the Board. The scope and purpose of the State Water Control Law is to protect and to restore the quality of state waters, to safeguard clean waters from pollution, to prevent and to reduce pollution and to promote water conservation. The State Water Control Law (Code of Virginia) §62.1-44.15 (10) 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, §62.1-44.15 (14) requires the Board to establish requirements for the treatment of sewage, industrial wastes and other wastes that are consistent with the purposes of this chapter. The specific effluent limits needed to meet the water quality goals are discretionary. The proposed amendments are to 9 VAC 25-720-80B. and would modify the existing waste load allocation for the South Hill WWTP (VA0069337), located in the Roanoke River Basin. The current WQMP was adopted by the Board at its August 31, 2004 meeting. As dictated in the WQMP, the South Hill WWTP is currently limited by an Apr-Nov, cBOD5 waste load allocation of 60.6 kg/d. The basis of the limit was a stream analysis and modeling effort conducted in 1991. In 1978, the Steady State CBOXYSAG model was calibrated and verified the South Hill discharge to Flat Creek. To be consistent with previous modeling efforts, the CBOXYSAG model was executed to generate effluent limits. The VPDES permit includes an expanded design flow of 3 MGD and corresponding seasonal limits for cBOD5 and TKN. The basis of these limits is the utilization of the Regional Model for Free Flowing Streams Version 4.10. In order to be consistent with previous modeling efforts, the same parameters were used in the updated modeling software. DEQ staff intends to recommend that the Board adopt the following modification for 9 VAC 25-720-80 B, for the South Hill WWTP (VA0069337): revise the cBOD5, Apr-Nov waste load allocation of 60.6 kg/d to cBOD5, Apr-Nov – 113.5 kg/d; and add cBOD5, Dec-Mar – 204 kg/d; TKN, Apr-Nov – 45 kg/d; and TKN, Dec-Mar – 56.8 kg/d. The public comment period will begin on May 22, 2017 and end on June 23, 2017. An advisory committee to assist in the modification of the WQMP will not be established. However, public comment on the use of an advisory committee is invited. Persons requesting the agency use an advisory committee and those interested in assisting should notify the DEQ contact person by the end of the comment period and provide their name, address, phone number, email address and their organization (if any). Notification of the composition of the panel will be sent to all applicants. Please note, all written comments should include the name, address, and telephone number of the person submitting the comments and should be sent to the DEQ contact person listed. Notice of this meeting and public comment period appears in the May 15, 2017 Virginia Register. | |||
