The Somerset Raritan Valley Sewerage Authority (SRVSA) incinerates its residual wastewater solids, as the primary method of sewage sludge disposal. Incineration reduces sludge volume and creates a stable product that can be landfilled. Recent federal air emission requirements of 40 CFR Part 62 Standards of Performance for New Stationary Sources and Emission Guidelines for Existing Sources: Sewage Sludge Incineration Units (SSI MACT Rule) require that SRVSA reduce the incinerator mercury emissions by approximately 96%. In order for SRVSA to achieve this level of mercury reduction, it is necessary to construct an air pollution control system utilizing carbon adsorption to scrub the incinerator flue gas.
The SRVSA is undergoing the Mercury Emission Control System Project in order to bring its incinerator into compliance with 40 CFR Part 62. The Mercury Emission Control System Project includes design, procurement, construction, and testing of an air pollution control system. The design has been completed and the General Construction Contract has been awarded. The Notice to Proceed was issued to Iron Hills Construction, Inc. on July 31, 2017.
As of February 20th, Iron Hills Construction, Inc. (General Construction Contractor or “GCC”) has completed all the required work for the project and has provided the Authority with the building and electrical Operation and Maintenance (O&M) manuals. The GCC has also provided the Design Engineer, CDM Smith, with the red line markups of the Contract plans in order for CDM Smith to generate as-built plans. Hankin Environmental Systems (Equipment Procurement Contractor or “EPC”) is finalizing the submission of the Mercury Emissions Control System O&M manuals and will be making final minor system adjustments.
The Authority has received the final test results from the Final Acceptance Testing (or “stack test”). CDM Smith has reviewed the stack test results and confirmed that all results are in compliance with the SSI MACT Standards. The project is now 100.0% complete.
As of January 29th, the Authority is still waiting for final test results from the Final Acceptance Testing (or “stack test”). Final test results are anticipated to be available in February. The Mercury Emission Control System is currently in full operation and the Authority has been continuously incinerating sludge for the past several months.
Iron Hills Construction, Inc. (General Construction Contractor or “GCC”) is continuing to complete the punch list items, which includes submittal of the final Operation and Maintenance (O&M) manuals. Hankin Environmental Systems (Equipment Procurement Contractor or “EPC”) has completed the final instrumentation and HMI adjustments and is also in the process of submitting the O&M manuals. To date, the project is estimated to be 99.5% complete.
As of December 12th, the Authority has completed the Final Acceptance Testing (or “stack test”). Final test results will be available in a couple of months. The Mercury Emission Control System is currently in full operation and the Authority has been continuously incinerating sludge for the past several months.
Iron Hills Construction, Inc. (General Construction Contractor or “GCC”) is in the process of completing the punch list items, which includes submittal of the final Operation and Maintenance (O&M) manuals.

(ESS) in late November. The stack test consists of collecting samples from the final exhaust stack and comparing the analyzed samples to the required permit limits. Successfully completing this test will verify that the new Mercury Emission Control System is performing as designed and will achieve the final milestone for this project (Compliance with SSI MACT Standards). It is anticipated that the test results will be available by early February, 2019. To date, the project is estimated to be 99.2% complete.
