Municipal Industrial Pretreatment Program

About

The City of York Municipal Industrial Pretreatment Program (MIPP) is responsible for implementing the national pretreatment program for the City of York Wastewater Treatment Plant sewer service area. The MIPP is tasked with enforcing all federal pretreatment standards and requirements in addition to any local sewer use regulations.

The MIPP accomplishes this through industrial facility inspections and industrial wastewater sampling. Inspections are performed to ensure industries conduct their manufacturing processes and operate their wastewater treatment systems in compliance with pretreatment regulations, and to prevent the discharge of unwanted substances to the sanitary sewer system and wastewater treatment plant. Wastewater sampling and testing allows the MIPP to evaluate industrial compliance with both federal and local wastewater discharge regulations. Some industrial facilities may be required to treat their wastewater before discharge to the sanitary sewer to meet federal and local wastewater regulations; hence, the term “pretreatment.” Wastewater test results are also used to recoup costs incurred by the City of York wastewater treatment plant to process the higher strength industrial waste- costs that would otherwise be borne by ratepayers. Personnel also investigate spills and discharges that may pose an environmental threat. MIPP has two full time staff.

Mission Statement

The MIPP is dedicated to providing effective and equitable enforcement of federal and local industrial wastewater regulations. MIPP will protect the environment, health of regional residents and workers, condition of the sanitary sewer system, and wastewater treatment plant processes. MIPP will accomplish this through the consistent application of regulations and policies, purposeful sampling and inspection activities, and keeping abreast of changes in regulations and industrial processes.

    Municipal Wasteload Management – General Information and Reporting

    Municipal Wasteload Management is a planning process whereby the owner or operator of a wastewater treatment plant (“treatment plant”) monitors both the volume and organic strength of the wastewater received by the plant and takes appropriate actions to prevent the treatment plant from receiving either too much flow or organic material for the treatment plant to treat properly. Municipal Wasteload Management also applies to owners or operators of sewage collection and conveyance systems and pump stations (“sewer systems”) who monitor flows or the usage of pumps to ensure that the sewer systems are capable of conveying flows to the treatment plant.

    All treatment plants and sewer systems owned by or serving a municipality are covered by the Department of Environmental Protection’s (DEP’s) Municipal Wasteload Management Regulations in Chapter 94 (available at http://www.pacode.com/, select “Browse” and “25 Environmental Protection”). The purpose of these regulations is to provide adequate sewage conveyance and treatment for future needs, prevent sewerage facilities from becoming overloaded, limit additional connections to overloaded facilities, correct overload conditions and prevent the introduction of industrial discharges into sewer systems that will interfere with operations or pass through the treatment plant. Ultimately, these regulations protect Pennsylvania’s waters from inadequately treated wastewater discharges.

    What are Chapter 94 Reports?

    DEP’s regulations at Chapter 94, Section 94.12 require that treatment plant permittees (“permittees”) submit two copies of an annual report to the appropriate DEP regional office by March 31 each year. These reports are generally called “Chapter 94 Reports.” The reporting period is the previous calendar year; for example, the report due by March 31, 2015, must cover the period of Jan. 1, 2014, through Dec. 31, 2014. Such reports must, in part, evaluate the existing and projected hydraulic and organic loads to treatment plants and sewer systems to determine whether such facilities should be upgraded. The report must be signed by the preparer and by the permittee.
