About this file
This file is an Attachment C detailing permit requirements for the Castle Point Wastewater Treatment Plant (WWTP) under New York State Department of Environmental Conservation (NYS DEC) SPDES Permit NY0020087. The document specifies comprehensive monitoring and effluent limitation requirements for the facility, including monthly testing for biochemical oxygen demand (BOD), total suspended solids (TSS), nitrogen/ammonia, and periodic coliform testing.
The permit outlines specific discharge parameters for the Hudson River, including daily and monthly limits for effluent concentration, with monitoring frequencies and sample types for various water quality indicators. Key requirements include maintaining BOD and TSS levels within 15% of influent concentrations, managing pH between 6.0-9.0 SU, and implementing seasonal disinfection from May 1st to October 1st. The document is directly related to the VA's solicitation for water and wastewater treatment plant operation and maintenance services at the Castle Point Campus, providing critical technical background for potential service providers.
