EnviroMed was the environmental consultant that performed waste characterization sampling for product within three discovered underground storage tanks (USTs).
The USTs were discovered during roadway work at the bridge site. EnviroMed obtained and sent samples of the product in the tanks to certified laboratory for a full RCRA waste characterization. Once the determination was made that the tanks contained gasoline that was considered to be hazardous waste, EnviroMed oversaw the proper pumping, cleaning, and removal of the tanks. EnviroMed wrote the specification of the UST removal based on federal and state regulations. Once the tanks were properly closed, EnviroMed sampled the UST gravesites. EnviroMed is familiar with the New York State DEC Regulations for gasoline USTs at closure. EnviroMed used these regulations for sampling protocols for the excavation grave samples.
Contamination of gasoline volatiles was found during the first round of soil testing. Remediation of soil was monitored by EnviroMed until closure samples met the criteria established by the DEC regulations. Waste characterization sampling and analysis were completed by EnviroMed prior to contaminated soil being transported to the designated facility.
Also, EnviroMed completed an investigation and sampling for three transformers related to the bridge structure. Three transformers within the south abutment of the Service House were opened and sampled for PCBs and for used oil parameters. Prior to sampling a map was developed to document the locations and conditions of the transformers. Each transformer was marked with a letter designation; samples were then collected in accordance with EPA’s Toxic Substance Control Act (TSCA) Regulations for PCBs. EnviroMed made relevant observations for any staining or impact to other surfaces (i.e., concrete, soil, metal). Samples were stored and sent to a certified laboratory for PCBs and used oil parameters. EnviroMed summarized the inspection and analytical results into a report that specified the type of waste in the transformers and their status under the EPA TSCA Regulations.
EnviroMed monitored conditions at a bridge site where several unidentified drums were observed. EnviroMed was called in to monitor air quality around the drums, observe environmental conditions around the drum, and sample the contents of the drums for waste characterization purposes. EnviroMed first suited up in the appropriate level of personal protective equipment, and then monitored the air for volatile organics, semi-volatile organics, oxygen content, carbon monoxide, hydrogen sulfide, and lower explosive limit, which are parameters typically analyzed by real time data instruments. After proceeding with caution, and after monitoring results were below permissible exposure limits, EnviroMed opened the drums using non-sparking tools. Individual samples were collected using the appropriate sampling jars, and then the jars were labeled with the specific information for each drum. Samples were then transported to a New York State certified laboratory.
In addition to meeting all the requirements and certifications of the request for proposal, EnviroMed staff’s extensive training in general safety and health procedures include work site safety, respiratory protection, right-to-know, electrical safety, as well as appropriate risk communication in dealing with the public (i.e. community groups), NYCDOT staff, environmental health, safety personnel, resident engineers and administrative staff. Separately, EnviroMed is fully knowledgeable concerning the requirements of the FEIS and the chain-of-command structure within the NYCDOT in the implementation of the independent monitoring procedures.
