DOWNLOAD EBOOKClam shells (Rangia) have been harvested from Lakes Poncahrtrain and Maurepas since 1933 by means of hydraulic dredges. The shells are used primarily in construction activities, but have a variety of other uses as well. There has been considerable controversy over the environmental impacts of shell dredging. This Final Environmental Impact Statement assesses the impacts of shell dredging in the lakes as permitted under 5-year permits issued in 1982 that will expire in December 1987. The document also addresses the impacts of applications for 10-year permit extensions that would allow shell dredging to continue under the same conditions. This volume contains the comment letters on the Draft Environmental Impact Statement received from Federal and state agencies and other interested parties. The letters are bracketed into specific comments. Responses to each specific comment are provided in Volume 3. The comments and responses are contained in separate volumes so they can be viewed side-by-side for ease of the reviewing public.

The shells are used primarily in construction activities, but have a variety of other uses as well. There has been considerable controversy over the environmental impacts of shell dredging. This DEIS has been prepared to assess these impacts. Numerous alternatives have been discussed and evaluated in the DEIS and two have been discussed in detail.

DOWNLOAD EBOOKThe approach taken in the present study was to select two sites in proximity that would also be representative of the area subjected to the perturbation cause by dredging operations. One site would serve as the control site and not be dredged; the second would be the experimental site and would be dredged in a manner approximating normal operations. Each site would be sampled in a quantitative manner both before and after dredging on a logarithmic time scale for the first year and on a quarterly basis thereafter. Ideally, the two sites would be located somewhere in the mid-lake region and would not ever have been dredged. Unfortunately, because dredging operations have occurred pretty much at random over the past 45 years with few, if any, records having been kept, it was virtually impossible to ascertain that any particular area had never been dredged. The next best alternative was to select an area that had not been dredged recently and that would be protected from being dredged again before the completion of the study. Such an area that had not been dredged recently and that would be protected from being dredged again before the completion of the study. Such an area exists along a two-mile wide swath, one mile on each side of the Lake Pontchartrain Causeway, which was first open in 1956.
