Weston & Sampson served as the environmental consultant on a complex, multi-year remediation of environmental impacts from a former Manufactured Gas Plant site. Project work included the remediation of MGP-impacted river sediment via surface water diversion and excavation of the river bottom. Approximately 30,000 tons of impacted sediment was removed for off-site treatment/disposal, and 13,000 tons of sediment was stabilized using Portland Cement. (Click on image at left for larger view.)
The New Hampshire Department of Environmental Services highlights this project in their March-April 2013 newsletter.
The Environmental Protection Agency has released the second draft of the New Hampshire General Permit for Discharges from Small Municipal Separate Storm Sewers (MS4s). Notice of the availability of the new NH Draft MS4 Permit was published in the Federal Register on February 12, 2013 and can be downloaded at https://federalregister.gov/a/2013-03055
As anticipated, there is a 30-day Public Comment Period for the draft permit. The comment period was originally scheduled to close on April 15, 2013, but was extended twice — first to May 15, 2013, and now until August 15, 2013. A public hearing took place March 14, 2013, at NHDES Pease Field Office, Pease International Tradeport, 222 International Drive, Suite 175, Portsmouth, New Hampshire.
