SCRD sees progress on site clean-ups
Almost 3,300 drycleaners are currently
covered by dedicated drycleaner remediation programs, according
to state drycleaner program managers from Alabama, Florida,
Illinois, Kansas, Minnesota, Missouri, North Carolina, Oregon,
South Carolina, Tennessee, Texas and Wisconsin who participated
in this spring’s State
Coalition for Remediation of Drycleaners (SCRD) meeting in St. Paul, MN..
Environmental assessment has begun at just
over 900 sites in these states, and remediation activities are
underway at about 250 sites. Remediation has been completed to
date at 66 drycleaner sites, and states have determined that
another 153 drycleaner sites have been closed under their state
programs. Closed sites include those that were closed after
only assessment work because contaminant concentrations were
below standards or clean-uo target levels; sites that were
closed after monitoring only where no remedial system was
installed); and sites that were closed after remediation was
performed.
Each state-mandated program is unique;
however, most consist of a fee or tax mechanism that funds
drycleaner site clean-uo, requirements that facilities or
parties must meet to be eligible for funding assistance, a
method for prioritizing drycleaner sites for funded clean-ups,
and regulations for implementing the program, usually on a
state-lead or reimbursement basis.
An overview of the drycleaner remediation
programs in all SCRD states, including the basic elements, fee
structures, and administrative information, is available on the
SCRD web site: www.drycleancoalition.org/survey.pdf.
SCRD also has database of more than 80
case studies focusing on remediation of drycleaner sites. The
information can assist public and private site clean-up
managers in making informed site remediation decisions. The
case studies are available on the SCRD web site,
www.drycleancoalition.org/profiles.
Since January 2004, new case studies on
drycleaner sites in Texas, Oregon, and Florida have been added
to the database. Many of existing case studies have been
updated. The profiles are searchable using key words entered by
the user.
States involved in or overseeing
drycleaner remediation projects are encouraged to submit case
study information, particularly lessons learned, for inclusion
in the SCRD database.
An on-line form and simple instructions
can be accessed from the SCRD web site at
www.drycleancoalition.org/profiles/form.cfm.
Two SCRD products in development. One of
these, to be released later this year, is designed to assist
other states anticipating focused drycleaner clean-up efforts.
It will describe the various approaches and alternatives SCRD
members have incorporated into drycleaning solvent clean-up
programs.
Also in process is a document that will
describe remediation technologies used to address chlorinated
solvents at drycleaning sites. This report will discuss the
pros and cons of different technologies, discuss institutional
controls, explore treatment train approaches, list parameters
used by regulators to determine whether to grant site closure,
and address indoor air removal/mitigation systems and vapor
treatment systems.
