Conversion from Class B to Class A Exceptional Quality, City of Chattanooga, TN

The City of Chattanooga personnel expressed an interest in pursuing Class A Exceptional Quality (EQ) designation for the biosolids generated from their JVAP Filter Press. Material Matters prepared a sampling plan and analyzed data from months of sampling events to support the Class A/EQ status for the JVAP system. We worked closely with Chattanooga personnel to develop protocols for processing and testing in order to meet state and federal standards. Based on analysis of the data collected, Chattanooga proved the JVAP process met Class A EQ criteria, allowing the City to have additional flexibility and options for the final disposition of their biosolids.

District of Columbia Water and Sewer Authority (DC Water), Washington DC

In 2002, the District of Columbia Water Authority (DC Water), formerly known as the District of Columbia Water and Sewer Authority, was interested in expanding their vast Class B biosolids land-application program into Pennsylvania. Material Matters assisted DC Water with the preparation of an application for the renewal of their Pennsylvania Department of Environmental Protection (PADEP) General Permit (GP) for the beneficial use of biosolids in PA. We gathered data from DC Water in support of the permit application, reviewed current biosolids operating data, prepared operational narrative of treatment processes, developed a biosolids-sampling plan, assembled and submitted the permit, and provided follow-up services requested by PADEP. Since the original submittal, Material Matters has developed and submitted two general permit renewals on behalf of DC Water.

Geo Specialty Chemicals, Allentown, PA

Material Matters assisted Geo Specialty Chemicals with the development of a strategy for beneficially using an industrial treatment plant residual in agricultural setting. To develop the program, we evaluated and characterized the residual, prepared the initial sampling plan, reviewed data generated from the initial sampling events, reviewed treatment protocols, prepared the PADEP application for statewide General Permit coverage, interacted with PADEP regarding feedback on the draft permit, located interested farmers, developed the farm management protocols, and assisted GEO with odor reduction strategies. Additionally, Material Matters has a multi-year contract with GEO to manage the residual material, including managing application data, generating regulatory reports, and overseeing farm and storage operations.

Conversion from Class B to Class A Exceptional Quality Biosolids, Borough of Columbia, PA

Material Matters, Inc. (Material Matters) was asked by the Columbia Municipal Authority to conduct a study to assess the feasibility, cost, and benefits of achieving Exceptional Quality (EQ) pathogen standards for Columbia Wastewater Treatment Plant (WWTP) biosolids. The request was based on issuance of an EQ General Permit by the Pennsylvania Department of Environmental Protection (PADEP) to a local treatment facility using lime post treatment. Columbia elected to pursue Class A EQ status based on the findings of the report, including low cost difference between Class A and Class B implementation, increased farm availability, and greater public acceptance. Material Matters assisted the Authority with establishing parameters for increased lime addition, developing sampling procedures and protocols, conducting a pilot test, and preparing the Class A EQ permit application to the PADEP. Columbia has operated under Class A EQ status for nearly 10 years.

Lehigh County Authority, Allentown, PA

In 2002, the Lehigh County Authority (LCA) submitted a biosolids permit renewal to the Pennsylvania Department of Environmental Protection (PADEP). After four years of correspondence between LCA and PADEP, a residuals permit was ultimately issued in place of the biosolids general permit renewal. LCA engaged Material Matters to review correspondence with PADEP to assess history of regulatory action; determine similarities and assess differences between the residuals GP and biosolids GP; identify challenges in transition, particularly operational items; and identify cost differential between facility and land-application program operation under residuals GP versus biosolids GP. In turn, Material Matters used scientific and regulatory support to prepare suggested language for revised permit conditions, held work sessions with PADEP, and ultimately negotiated permit modifications with PADEP, which met LCA's needs.
