Re: Chromium Electroplating Emission Standard:
Compliance Extension Request
Dear Mr. Miller:
On June 30, 1995, DELPHI Energy & Engine Management Systems
(DELPHI) sent an initial notice to the United States Environmental
Protection Agency (U.S. EPA), Region 5. This notice informed Region
5 that DELPHI operates a decorative chromium electroplating tank
at the companys Flint, Michigan facility (Flint tank). Such tanks
are subject to the National Emission Standard for Chromium Emissions
from Hard and Decorative Chromium Electroplating and Chromium
Anodizing Tanks, 40 CFR part 63, subpart N (chrome standard).
The compliance provisions of this standard, 40 CFR Section 63.343,
require that decorative chromium electroplating tanks comply no
later than January 25, 1996.
The compliance provisions allow a source to request up to one
additional year to comply with the chrome standard. On October 10,
1995, you sent Region 5 a letter requesting a four month compliance
extension for the Flint tank. Your letter states that DELPHI will
comply by shutting down the Flint tank. However, the company must
first complete union negotiations and find a qualified supplier
of chrome-plated parts for the facility. Region 5 finds this request
reasonable.
On August 7, 1995, the U.S. EPA Administrator delegated the authority
to grant compliance extensions to the Regions. Under this authority,
Region 5 extends the chrome standard compliance date for the DELPHI
Flint tank to May 25, 1996. Region 5 grants this extension
on one condition. DELPHI must notify the U.S. EPA and the Michigan
Department of Environmental Quality, in writing, when it shuts
down the Flint tank.
If you have any questions on this matter or the chrome standard,
please contact Karen L. Bell, of my staff, at (312) 353-8640.
Sincerely yours,
Valdas V. Adamkus
Regional Administrator
