I. have reviewed the document and the accompanying EA and have circulated it to our Technical Support Branch. Below is a summary of our comments. The scope of the EA in terms of covering both primary and secondary as well as short and long term impacts was generally good. However, in the discussion of secondary nonpoint source impacts under Water Quality on page 14, the final sentence in that section appears to be misleading or in need of elaboration. Is the Town really planning on implementing a stormwater management policy that would addressthe impacts of stormwater on water quality? If yes, they are to be commended and details should be provided. If no, the statement should be deleted. If implementation of such a policy is not being planned, the discussions on water quality under Section C. (Adverse Impacts Which Cannot Be Avoided and Mitigative Measures) must be revised to accomodate this change. See also the June 25, 1990 memo from Juan Mangeles of our Technical Support Branch (attached). He identifies several items which need to be corrected or elaborated on. Most of his comments pertain to the level of assessment of the direct water quality impacts in the EA. With the exception of those items presented above, the document appears to be acceptable. Please contact either Juan or me if you have any questions. Kinston.Mem SEPA 1 DIVISION OF ENVIRONMENTAL MANAGEMENT MEMORANDUM TO: Alan Clark FROM: Juan C. Mangles THROUGH: Carla Sanderson Trevor Clements 64/ SUBJECT: June 25, 1990 Amendment No. 2 to the 201 Facilities Plan Kinston Northside (NC0024236) and Kinston Peachtree (NC0020541) Wastewater Treatment Plants Lenoir County The Technical Support Branch has reviewed the subject Amendment of the 201 Facilities Plan for the City of Kinston Northside and Peachtree WWTP's. Our review indicated that all significant issues of concern are properly addressed for the basic design of the additional facilities. However, the environmental assessment (EA) of the proposed project failed to specifically address the adverse/beneficial water quality impacts associated with the proposed addition of phosphorus removal and dechlorination facilities. The EA did not elaborate on the effect of the discharge on dissolved oxygen, NH3-N, total nitrogen, BOD5, and toxics concentrations in receiving waters which are near exhaustion of their assimilative capacity. The EA report only notes that "disposal of effluents into the receiving streams is not expected to have a significant impact on the receiving streams as the proposed treatment facilities are planned to produce effluent quality that will protect the current assigned water quality." Although, the Technical Support Branch does not anticipate additional adverse water quality impacts at the existing flows, we feel that the EA should have addressed, in detail, the impact of the aforementioned parameters in the Neuse River system due to the discharge from the existing and proposed treatment works. Finally, the report erroneously indicates that DEM requires compliance with the 2 mg/1 total phosphorus limitation in 1995. Please note that in January, 1988 the Environmental Management Commission stipulated a target compliance date of May 1, 1993 for existing facilities with design flow rates of 0.5 MGD or greater in the Neuse River basin.
