Mr. Lyman Austin Regional Manager Ready Mix Concrete Company 411 Valley Forge Rd Hillsborough, NC 27278 Michael F. Easley, Governor William G. Ross Jr., Secretary North Carolina Department of Environment and Natural Resources SUBJECT: Compliance Evaluation Inspection Ready Mix Concrete Company -Hillsborough Permit Number— NCG140250 County - Orange Dear Mr. Austin: Coleen H. Sullins, Director Division of Water Quality On February 13, 2008, Autumn Hoban, of the Division of Water Quality (DWQ), Raleigh Regional Office, performed a stormwater compliance evaluation inspection of the Ready Mix Concrete Company Plant #53 in Hillsborough. The staffs assistance and cooperation was helpful and appreciated. Inspection findings are listed below. �Indu6try4ndiSite De§criptiona Ready Mix Concrete Company mixes concrete on -site for delivery to construction sites, road projects, and residential customers. Stormwater runoff and process wastewater. generated at such facilities is regulated by General Permit NCG140000. DWQ has therefore issued Ready Mix Concrete Company certificate of coverage, NCG140250, which became effective on August 1, 2004 and expires on July 31, 2009. The facility has a settling pond. The stormwater and wash water on -site is directed to the settling pond. The facility has one stormwater outfall that receives the overflow of the settling pond during rain events or during times when the pond level is high. The pond level was well below the overflow the day of the inspection and due to drought conditions of the past year, appears to have very little to no discharge occurring. p _ ton:Summaryr�i1,K "_ X'� The facility keeps records and was in compliance with permit requirements. The Stormwater Pollution Prevention Plan was reviewed, however, no documentation was dated for the review in the facilities records. It is recommended that a letter be drafted each year and placed in the file to indicate that the plan was reviewed, even in the event that no updates are necessary. 3400 Barrett Drive One Raleigh, North Carolina 27609 NorthCarolina Phone:919-791-4200 Fax:919-788-7159 Nat'/rully \O�0 WA7F9OG Michael F.
