Presenting Alternatives
On October 7, 2009 the district responded by a letter outlining the engineering studies done from 1993-1995 that concluded with two alternatives: an upgraded plant with lateral gravel filters as well as conveying the effluent to Torrington. The letter stated that the DEP approved this concept on July 8, 1996 and work on conceptual designs proceeded in 1997. However, in December 2002 the DEP indicated lateral gravel filters were no longer an option and changed other conditions also. This required further work on the district’s part, which concluded with our 2005 scope of the study.
The 2005 Study did not provide a preferred alternative as we were waiting for the DEP’s review and comments on the technical merits of our study. The district also requested a written copy of the DEP’s “statement of practice” that was referred to by the DEP as the standard against which alternatives were being evaluated. Once the district had time to review the DEP’s statement of practice and its technical comments, the district indicated it would provide a written response by January 1, 2010.
