Maryland Mass Transit Administration Environmental Services

Client: Mass Transit Administration (MTA) Maryland Department of Transportation

Location: Baltimore, Maryland

Services: Regulatory compliance, auditing and reporting; spill prevention and response plans; site, facility and field investigations; stormwater management; UST/AST services

As part of a comprehensive on-call contract, KCI has provided comprehensive environmental and remediation services including the following task orders:

Indoor Air Quality and Industrial Hygiene Investigation – KCI performed an investigation and inspection of the Bush Street Maintenance Facility to determine the nature and extent of indoor air quality problems. As a result of the phase I investigation, a quantitative analytical strategy was developed to confirm the nature and extent of the problem and obtain information that facilitated the remedial action/design. KCI staff conducted air sampling, a ventilation survey, and a visual site inspection to identify hazardous materials. KCI reviewed the design, configuration, and maintenance/service reports and schedules for the facility exhaust system. KCI’s remedial design included modifying the exhaust system, brake maintenance facility, dust control system, and the oil water separator system.

Discharge Permit Compliance – At the Bus Cleaning and Maintenance Facility, KCI acted as liaison with Maryland Department of the Environment (MDE) on behalf of MTA. KCI requested and received permission to use biomonitoring to evaluate wastewater toxicity at an outfall. Using the results of the initial field reconnaissance, KCI investigated the feasibility of rerouting the outfall from the storm drain system to the sanitary sewer and adding an oil/water/grit separator. KCI will seek to have the facility’s site-specific NPDES permit down-classed to a general permit.

Geotechnical Evaluation and Environmental Site Characterization – MTA requested that KCI investigate the subsurface conditions of the Bush Street Complex, due to concerns regarding excavating potentially hazardous or petroleum-contaminated soils during replacement of an existing storm drain. The complex consists of buildings, paved roadways, and parking areas for public transportation buses.

During the design phase, KCI explored the subsurface conditions using soil borings and analyzed the soils for geotechnical properties, VOCs, SVOCs, BTEX, TPH, Diesel and Gasoline Range Organics, Metals, Pesticides, and PCBs. Based on the results, KCI developed geotechnical and environmental recommendations for the earthwork, pavement sections, soil disposal, and other geo-environmental concerns. In order to ensure structural integrity of the storm drain and minimize excavation of contaminated soils, KCI provided recommendations and specifications for undercutting and removing unsuitable fill soils and replacing the undercut material with a geosynthetically stabilized subbase. KCI also negotiated with MDE and developed specifications for handling, treatment, storage and disposal of petroleum contaminated soil and groundwater.

Stormwater Pollution Prevention Plan – At the Bush Street Maintenance Facility in Baltimore City, KCI conducted a facility inspection to determine work practice modifications needed to comply with NPDES regulations. KCI developed and implemented a Storm Water Pollution Prevention Plan (SWPPP) and identified best management practices (BMPs) for preventing pollutant runoff.
