Lyman-Richey Corporation

Concrete batch plants throughout Nebraska

The overall goal of this project was to design Industrial Stormwater Pollution Prevention Plans (SWPPPs) for concrete batch plants that would comply with the regulations and guidelines set forth by the Nebraska Department of Environment and Energy. E&A designed the SWPPPs in 2011 and re-permitted the concrete batch plants in 2016 for Ready Mixed Concrete Company, and the subsidiaries of Lyman-Richey Corporation; Shamrock Concrete Company, Siouxland Concrete Company and Gerhold Concrete Company. Located throughout the City of Omaha and State of Nebraska, E&A also worked with local officials and ordinances in order to maintain SWPPP compliance in each municipality.


The State of Nebraska authorizes the discharge of stormwater from industrial activities under the National Pollutant Discharge Elimination System (NPDES) General Permit. The Lyman-Richey facilities are permitted under SIC Code 3272, Sector E – Glass, Clay, Cement, Concrete and Gypsum Product Facilities. The SWPPPs were designed to prevent stormwater from coming into contact with concrete batching, truck fueling and aggregate storage piles. E&A also assisted with correspondence between Lyman-Richey Corporation and the State of Nebraska regarding the fulfillments of their benchmark monitoring requirements.
