This section 93102.4 sets forth requirements that apply to
all hexavalent chromium hard and decorative chromium electroplating and chromic
acid anodizing facilities, except for facilities subject to section93102.6
(i.e., facilities that perform electroplating using a trivalent chromium bath
or are facilities with enclosed hexavalent chromium electroplating tanks). The
requirements differ depending on whether a facility is an existing facility, a
modified facility or a new facility. Additional requirements that apply to all
facilities (i.e., all existing, modified, and new facilities) are contained in
section 93102.5, sections 93102.7 through 93102.14 and section 93102.16.
Subsection (a) contains the requirements to reduce
hexavalent chromium emissions that were in effect before October 24, 2007. The
limits in subsection (a) shall remain in effect for a facility until the limits
in subsection (b) become effective. Once the limits in subsection (b) become
effective for an individual facility the limits in subsection (a) no longer
apply.
The limits in subsection (b) are phased in depending on the
amount of annual permitted ampere-hours and the distance to the nearest
sensitive receptor. Depending on the facility, limits in subsection (b) become
effective on April 24, 2008, October 24, 2009, October 24, 2010, or October 24,
2011.
(a) Requirements that Apply to
Existing Hexavalent Chromium Electroplating and Chromic Acid Anodizing
Facilities.
An existing facility is a facility that is in operation
before October 24, 2007.
In addition to the limits specified in this subsection (a)
all facilities (i.e., all existing, modified, and new facilities) must comply
with the applicable provisions contained in section 93102.5, sections93102.7
through 93102.14, and section 93102.16.
(1) Limits that Apply to Existing Hard
Chromium Electroplating Facilities Until the Limits in subsection 93102.4(b)
Become Effective.
During tank operation, each owner or operator of an
existing, facility shall control hexavalent chromium emissions discharged to
the atmosphere from that facility by reducing the hexavalent chromium emissions
from the add-on air pollution control device(s) serving the electroplating
tank(s) as identified below.

(C) Special Provisions that Apply
for some Hard Chromium Electroplating Facilities Using Less than or Equal to
500,000 Ampere-hours per Year Until the Limits in subsection 93102.4(b) Become
Effective.
The permitting agency may approve, on a case-by-case basis,
alternative standards for hard chromium electroplating facilities using less
than or equal to 500,000 ampere-hours per year. The operation must have been
constructed on or before December 16, 1993. At a minimum, the facility must use
a chemical fume suppressant containing a wetting agent to lower the surface
tension of the plating bath to at least 45 dynes per centimeter (dynes/cm)
(3.1x10-3 pound-force per foot [lbF/ft]). Effective April 24, 2008, the
chemical fume suppressant used by the facility must meet the criteria specified
in section 93102.8 and the surface tension shall be maintained below the value
specified in Table 93102.8. The permitting agency may require additional
emission reduction techniques as necessary to reduce the public health impact
of emissions from the operation. The owner or operator must comply with the
applicable parameter monitoring [section 93102.9], recordkeeping [section
93102.12], and reporting [section 93102.13] requirements. If an emission
reduction technique not identified in this rule is used, the owner or operator
must submit a plan to the permitting agency describing the alternative
technique and identifying appropriate monitoring, recordkeeping, and reporting
requirements. The permitting agency, with U.S. EPA concurrence, shall approve
this plan if equivalent results are obtained. Upon approval, the requirements
identified in the plan shall be the applicable requirements under this
regulation.
(2)
Requirements that Apply to Existing Hexavalent Decorative Chromium
Electroplating and Chromic Acid Anodizing Facilities Until the Limits in
subsection 93102.4(b) Become Effective.
During tank operation, each owner or operator of an
