Bay Park Sewage Treatment Plant Effluent Diversion to Cedar Creek Water Pollution Control Plan

Environmental Planning & Management, Inc. (EPM) completed a Phase I Environmental Site Assessment (ESA) and Phase II Environmental Investigation for the proposed Effluent Diversion of Wastewater from the Bay Park Sewage Treatment Plant (STP) to the Cedar Creek Water Pollution Control Plant (WPCP) Ocean Outfall.

The Phase I ESA was conducted to identify potential sources of hazardous or contaminated materials that could impact project construction and operation.  The assessment consisted of a visual site reconnaissance to observe for signs of the use, storage or release of hazardous materials within, or abutting, the project corridor; review of historic Sanborn Fire Insurance Maps and review of federal, state, and local agency environmental records.

The Phase II Environmental Site Investigation was completed to identify subsurface environmental conditions.  Soil and groundwater samples were collected for environmental laboratory analysis and were analyzed for Volatile Organic Compounds (VOCs), Semi-VOCs, Polychlorinated Biphenyls (PCBs), Pesticides, Total Petroleum Hydrocarbons (TPH), and Target Analyte List (TAL) Metals. Selected soil samples were also analyzed for Toxicity Characteristic Leaching Procedure (TCLP) RCRA 8 Metals to determine if the material could require disposal as a regulated hazardous waste.

EPM prepared a Hazardous and Contaminated Material Screening Assessment Report and a Phase II Environmental Investigation Findings Report summarizing findings, data collection techniques, analysis procedures, and locations and quantities of confirmed hazardous materials.

Milburn Creek Culvert Improvements

EPM completed an environmental soil investigation for the Merrick Road over Milburn Creek Culvert Rehabilitation Project.  The project will make repairs to the existing concrete box culvert that connects Milburn Pond to Milburn Creek beneath Merrick Road.

The investigation was performed to determine the environmental quality of soil within the limits of excavation for the project since there was potential for project soils to be impacted with petroleum due to a former gasoline filling station that once occupied the abutting property.

EPM prepared a Soil Investigation Report summarizing findings, data collection techniques, analysis procedures, and locations of confirmed contaminated soil.  Also included were recommendations for proper removal and disposal of impacted soil.

Lawrence/Cedarhurst Water Pollution Control Plant

EPM performed Asbestos Surveys at the Lawrence/Cedarhurst Water Pollution Control Plant.  The purpose of the surveys was to investigate if waterproofing material was present in various buildings and to sample it for asbestos content.

The following structures were surveyed:

• Lawrence Building F –  brick façade

• Lawrence Building C – windows

• Cedarhurst Screening Building – brick façade

• Cedarhurst Pump Building – brick façade

• Cedarhurst Sludge Control Building – brick façade

• Cedarhurst Office / Lab Building – brick façade

• Primary Digester Tank – known asbestos containing mastic below face brick façade

EPM prepared an Asbestos Survey Report summarizing findings, data collection techniques, analysis procedures, and locations and quantities of confirmed asbestos containing materials.
