Re-Evaluation of Local Limits and Pretreatment Program Assistance, Greater Hazleton Joint Sewer Authority, Hazleton, PA

Material Matters personnel assisted the Greater Hazleton Joint Sewer Authority (GHJSA) with a re-evaluation of the discharge limits, known as Local Limits, on the industrial wastewater discharged by significant and categorical industrial users to the plant. The Re-Evaluation process included a review of the existing analytical results to establish a list of “pollutants of concern”. Ultimately, thirty two (32) pollutants of concern were identified and included in the Re-Evaluation. A sampling plan was developed to provide additional data. Using these data, the “Headworks Analysis”, was performed to establish the Maximum Allowable Headworks Load (MAHL). The Headworks Analysis calculations were performed using a custom spreadsheet providing a logical, step-wise approach to the evaluation, and allows for easy updating and revisions.

Re-Evaluation of Local Limits and Pretreatment Program Assistance, The City of Hagerstown, MD

As part of its Maryland Department of Environment (MDE)-approved Municipal Industrial Pretreatment Program (MIPP), the City of Hagerstown imposes discharge limits, known as Local Limits, on the industrial wastewater discharged by significant and categorical industrial users. A re-evaluation process was conducted that included a review of the existing analytical results to establish a list of “pollutants of concern”. Ultimately, eighteen (18) pollutants of concern were identified and included in the re-evaluation. A sampling plan was developed to provide additional data. Using these data, the “Headworks Analysis," using a custom spreadsheet providing a logical, step-wise approach to the evaluation, was performed to establish the Maximum Allowable Headworks Load (MAHL). A portion of the MAHL was allocated to permitted industries in the form of a Maximum Allowable Industrial Load. The Headworks Analysis calculations were performed. Ultimately, Local Limits were successfully developed, approved, and implemented for fifteen (15) parameters.

Identification and Mitigation of Elevated Molydenum Loadings, Lehigh County Authority, Allentown, PA

Following a sudden and dramatic increase in molybdenum in two sequential treatment plants, Material Matters worked with LCA to implement strategies for the identification, recovery, and mitigation of molybdenum loading at their pretreatment facility, City of Allentown WWTP, and its biosolids farm storage. The Mo loading was traced to a hauled-in waste vendor and then back to a metals processing facility. Data mining and fitting the data to expected response curves helped identify the loading over time as it moved through both plants, which was used to project the additional time needed to landfill the dewatered biosolids. Cleanup and management strategies along with new SOPs were developed to limit cleanup costs, meet all environmental requirements, and satisfy PADEP that upgraded data collection and management, hauled-in waste program oversight, and communication protocols are all in place to prevent an incident of this scope from occurring again.

Re-Evaluation of Local Limits and Pretreatment Program assistance, Scranton Sewer Authority, Scranton PA

As part of its United States Environmental Protection Agency (USEPA)-approved Municipal Industrial Pretreatment Program (MIPP), the Scranton Sewer Authority (SSA) imposes discharge limits, known as Local Limits, on the industrial wastewater discharged by significant and categorical industrial users. In 2007, the SSA pursued re-evaluation of their local limits which had not been updated in 15 years. The evaluation process included a review of the existing analytical results to establish a list of “pollutants of concern”. Ultimately, thirty six (36) pollutants of concern were identified and included in the Re-Evaluation. A Sampling Plan was developed to provide additional data. Using these data, the “Headworks Analysis”, was performed to establish the Maximum Allowable Headworks Load (MAHL). Ultimately, the Re-Evaluation process successfully satisfied the CO&A and Local Limits were developed and implemented for thirteen (13) parameters.
