Advance   Identification (ADID)
        Advance Identification of disposal areas
  (ADID) is an advance planning process under
  which EPA, in cooperation with the Corps of
  Engineers and after consultation with the State,
  may identify wetlands and other
  waters which are either gener-
  ally suitable or unsuitable for
  the discharge of dredged and
  fill material prior to the receipt
  of a Section 404 permit applica-
  tion. The ADID process gener-
  ally involves collection and dis-
  tribution of information on the
  values and functions of wetland
  areas.  This information pro-
  vides the local community with
  information on the values of
  wetland areas that may be af-
  fected by their activities as well
  as a preliminary indication of
  factors which are likely to be
  considered during review of a
  Section 404 permit application.
   lixperience shows that
local cooperation and sup-
port are vital to the suc-
cess of the ADID project.

Recently, ADID's have
been initiated by local en-
tities in order to facilitate
local planning efforts.
                                While an ADID study generally classifies
                         wetland areas as suitable or unsuitable for the
                         discharge of dredged or fill material, the classifi-
                         cation  does not constitute either a permit ap-
                                          proval or denial and should
                                          be used only as a guide by
                                          landowners and project pro-
                                          ponents in the planning of fu-
                                          ture activities.  The nature of
                                          the classification is strictly ad-
        The ADID process is in-
  tended to add predictability to
  the wetlands permitting pro-
  cess as well as better account
  for the impacts of losses from
  multiple projects within a geo-
  graphic area. The process also
  serves to inform the local popu-
  lation of the values and func-
  tions of wetlands in their area,
  and it generates environmental
  information valuable for other
              These efforts have proven
              to be the most successful
              iv.iy for generating sup-
              port for wetlands protec-
                Because they are usu-
              ally based on watershed
             planning, ADIDef tofts j re
             extremely compatible
             with geographic and eco-
             system initiatives such as
             H'A's Watershed Protec-
             tion Approach.
   As of December 1992, there
were 35 completed  ADID
projects, and 36 are  ongoing.
ADID projects have ranged in
size from less than 100 acres to
greater that 4,000 square miles,
and are located from Alaska to
Florida.  Advance Identifica-
tion projects can be resource
intensive activities, although
some have been completed in
as little as 6 months.  Regional
experience seems to indicate
that the smaller or more local
the ADID project boundaries,
the more complete and effec-
tive the ADID analysis and re-
sults.  EPA has seen an in-
crease in interest in ADID, and
expects more States, localities,
and private organizations to
become involved in providing
funds and otherwise support-
ing ADID or other comprehen-
sive planning efforts.
