RCRA Facility Investigation and Corrective Action—Dry Cleaning Operation

GEMG personnel developed and implemented a RCRA Facility Investigation work plan for characterization of on-site and off-site impacts from a dry cleaning operation in Metro Denver.  The work plan was implemented and a RFI RCRA Facility Investigation Report was submitted to the Colorado Department of Public Health and Environment (CDPHE) for approval.  The agency approved the report under the state’s Integrate Corrective Action Plan (ICAP) program.  ICAP activities are underway.


Lead Cleanup Consulting and Database

GEMG personnel provided consulting services to assist the City of Joplin in evaluating the U.S. EPA study of the potential health effects of lead from past smelter activity in and around the City.  GEMG personnel services included review of U.S. EPA documents, review of analytical data on blood lead, preparation of an analytical database for use by the City and U.S. EPA for tracking blood lead data, and attendance at public meetings.  The development of the analytical database resulted in a geographic plot of Joplin about the distribution of lead.  GEMG personnel have assisted with technical questions regarding lead exposures and eased citizens’ fear of the lead contamination.

Site Investigation, Remedial Action, Closure Plan—Brass Foundry

The Mueller Brass plant is a nonferrous metals manufacturing plant located north of Detroit.  The plant has been in operation since 1917.  The plant entered into a consent decree with the State of Michigan in 1991.  GEMG personnel have been providing technical consulting to Mueller since the development of the consent decree.  The consent decree covers both surface water quality (NPDES permitting) and Michigan Act 307 soil contamination investigations and remediations.


GEMG personnel have furnished comprehensive consulting services to support the client in the resolution of a Consent Decree reached with the State of Michigan Department of Environmental Quality (MDEQ) and an environmental group over the discharge of storm water via an outfall to a tributary of the lower Great Lakes and alleged soils contamination at a brass foundry in Michigan.


Since early 1991, GEMG personnel have provided technical consulting to the client in the two areas of the Consent Decree (storm water discharges and soils contamination).  GEMG personnel assisted with the resolution of the technical aspects of the Consent Decree including development of interim discharge limits of the outfall.
