On July 9 - 10,1998,1 traveled to the site subject above in order to identify and documentany wetland environments that may be affected by contamination at the site and/or impacted byremoval/remedial activities currently being planned. The following are the conclusions aboutthejurisdictional status of areas identified during the field investigation:
• The onsite inspection revealed five significant areas (see map. Attachment 1),that met the criterion (i.e., predominance ofhydrophytic vegetation, hydric soil andwetland hydrology) necessary to establish wetlands subject to federal regulatoryjurisdiction under the Clean Water Act. Wetlands were jointly defined by EPA andthe Corps of Engineers (COE) in 1977, as "those areas that are inundated orsaturated by surface or ground water at a frequency and duration sufficient tosupport and under normal circumstances does support, a prevalence of vegetationtypically adapted for life in saturated soil conditions" (EPA, 40 CFR 230.3).
The attached map and field data forms (Attachment 2) document the visualobservations made during the field investigation.
• The following is an estimate of the size (in acres) of the wetland resources:
east side of site - 3.8• north drainage pathway - . . . . . 0.3
Selser's Creek - 0.4- souSh drainage pathway - 1.8
isolated wetland - 0.1 (west of Furnace Bidg.)Total = 6.4 acres
• The same general areas were previously mapped by John Murell, Ecology andEnvironment, during his removal investigation (i.e., Mr. Murell documented areasthat were inundated by surface water from January through March 1998,Attachment 3).

The wetland resources that were historically found adjacent to Selser's Creekhave been significantly impacted by previous dredging operations (i.e., most likelythe Tangiapahoa Parish Police Jury for flood control purposes). Presently thewetlands in this area are represented only by narrow vegetated strips (i.e.,approximately five to ten feet in width below the plane of ordinary high water) oneither side of the improved channel.
Finally, significant wetland resources (i.e., coastal swamp and Bottomlandhardwoods) are located approximately 0.35 miles downstream of the site. Thedownstream resources were also identified by Steve Cowan, Ecology andEnvironment, while conducting sampling activities for EPA's Site InvestigationReport, dated March 31,1997. These resources are also indicated on the 19941:24,000 USGS Quadrangle Map, Ppnchatoula, Luoisiana.
