APR.23.1998 10:06AM 4ISC DNR SOUTHERN DIST HQTRS NO.172 P.2/3 CORRESPONDENC:E/MEMORANDUM State of Wisconsin DATE: April 23, 1998 FILE REF; TO: Mark Roffers -Dane County Planning and Development Department CC; FROM: Steven f ix .R//4/1--- SUBJECT; Comma its on Proposed Payne and Dolan Gravel Extraction Site Department of Natural:tesources South Central Region staff have reviewed materials submitted by Payne and Dolan(MD)and their consultant regarding the proposed development of a gravel extraction operation near the Sugar River and Badger Mill Creek just south of the City of Verona. We offer the fc Mowing comments and concerns, Our first concerns regal ding this site when the preliminary proposal was presented were possible impacts on groundwate,•and direct impacts on the Sugar River and Badger Mill Creek. P&D employed Woodward Clyde as consultants to address our concerns as well as other which may arise. Woodward Clyde conducted a groundwater hydrology study of the area.Number of conclusions came out oa'that study, First, local water supply wells will be minimally affected by this operation. Second, :here would be only one small reach of Badger Mill Creek downstream of STH 69 where groundm ater discharge to the stream might be decreased due to development of phase II of the proposec project. Other concerns of the DNR were over the need for any Chapter 30 permits or wastewatvr management permit,possible incursion of the operation into the floodplain, construction site erosion control, air quality issues, and stormwater management, The proposed project w 11 not include any pond creation within 500 feet of either the Sugar River or Badger Mill Creek sc a Chapter 30 permit will not be necessary. Wash water from stone and gravel processing will b e taken from the created ponds,treated onsite and recycled back into the pond thus eliminating the requirement for any WPDES wastewater discharge permit.An air quality permit will not I e required. The last revision of the project plan indicates that the area on the project site north of Badger Mill Creek will not be developed. This plus the 500 foot or land side of the floodplain di Stance ought to prov:.de an adequate buffer to both streams from a surface water quality and wildli:e habitat standpoint. Construction site erosion control will be handled via the county's erosion control ordinance and the requirements of Wisconsin Administrative Code NR 216, so we do not foresee any problems as long as the measures are implemented and maintained according tc the Dane County approved plan for the site, Stormwater from the adjacent land will be dii ected around the extraction areas.Adverse impacts on local water wells from this project,while not expected,will be handled by P&D as part of their Dane County requirements.
