The EPA conducted an unannounced site visit of the Clifton Street Sewer Separation and Water Main Replacement Projects in the City of Portland, Maine, from June 15 through June 17, 2009. The projects were performed jointly by the City of Portland, Maine (sewer separation) and Portland Water District (water main replacement). We toured the projects and interviewed city representatives, water district representatives, and contractor personnel. We also reviewed documentation related to Recovery Act requirements. We conducted our field work phase from June 15, 2009, to April 7, 2011. Our work was suspended for a period of time prior to completion. Based upon our site visit, no issues or concerns came to our attention that would require action from the city, the Portland Water District, or the U.S. Environmental Protection Agency.
