11 Background

On November 20 198S the Federal Regisler (SO FR 47946) published an EPA Memorandum

on CERCLA Compliance With Other Environmental Statutes One of these statutes is Executive

Order 11990 promulpled 10 insure the conservation of wellands

The lbove Elltocu1ive Order requires that action be liken 10 minimize the destrudion loss or

dqrodalion of wetlands and 10 _ and enhanoe the natural and beoefuial values of the

wellands The Order also emphasizes the imponancc of avoidinJ any activity in wetlands unless

there is no pnclicable aloemative and minimizing or mi1igating the harm to wetlands if the only

- ~ pnclicable aloemative requires activity in the wetland

J1eaioa I EPA bas reqllelled that a wellands ~ be performed for the Dulinamp Hill

Project A Wdlands delineation wu performed on Aprill3 and 14 1990 in acoonlanoe with

criteria and mothodolocY ciled in the RifFS Work Plan (ESE I990a) The followinamp are the

raulu of this lllldy

The General Study Area (herein refened to as Study Area) islocaled berween the East and West

Branches of the Passumpsic River (Fiaure 1) Both branches of the river rnerae just north of

the town of Lyndonville Vermont (Caledonia County) The Study Area includes the Disposal J Area located on the western side of Darling Hill Road in addition to the several monitoring

weU locations (see Figure 1) The main ponions of the Study Area lie on the top and along the

western slopes of a ridge that lies between the two branches of the Passumpsic River Darling

Hill Road runs in a northeasterly direction across the top of this fairly steep ridge (Figure 3) -)

The field identification of jurisdictional wetlands is based upon the Federa1 three parameter

(vqetation soils and hydrology) methodology The criteria to be evaluated are outlined in the

d Federal Manual for Identifying and Delineating Jurisdictional Wetlands (FICWD 1989) A brief

synopsis of these criteria are presented below

Under Section 404 of the Clean Water Act fcdcnlly regulated wetlands are defined as follows

those areas that are inundated or saturated by surface or sroundwaur at a freshyquency and duration sufficient to support and that under normal circumstances does support a prevalence of vqelation typically adapled for life in saturaled ooil conditions [33 CFR 3283(b) In Federgtl Rqister ~1(219)41206-41260 1986)

these constituents in the Passumpsic River sediments sampled downstream of the Disposal Area

As elevated concentrations were not observed it appears that the total mass flux of COC is not

glQt enough to pose a threat to the wetland environment This is most likely a reflection of the

disparity between the very large dischiJle of the Passumpsic River versus the very small dismiddot
