(B) Reports of performance test results. The owner or operator shall report performance test results to the permitting agency. Reports of performance test results shall be submitted no later than 90 days following the completion of the required performance test, and shall be submitted as part of the notification of compliance status required by paragraph (2) of this subsection.
(C) The content of performance test reports is identified in Appendix 1.
(2) Initial compliance status report. An initial compliance status report is required each time that a source becomes subject to the requirements of this section. The owner or operator shall submit to the permitting agency an initial compliance status report, signed by the responsible official who shall certify its accuracy, attesting to whether the source has complied with this rule.
(A) Initial compliance status report due date.
1. For sources required to conduct a performance test, the initial compliance status report shall be submitted to the permitting agency no later than 90 calendar days following completion of the compliance demonstration.
2. For sources that are not required to complete a performance test, the initial compliance status report shall be submitted to the permitting agency no later than 30 days after the effective date of this rule for existing sources, or at start-up for new sources.
(B) The content of the initial compliance status report is identified in Appendix 2.
(3) Ongoing compliance status reports. The owner or operator shall submit a summary report to the permitting agency to document the ongoing compliance status.

(B) The content of ongoing compliance status reports is identified in Appendix 3.
(4) Reports of breakdowns. The owner or operator shall report breakdowns as required by the permitting agency's breakdown rule.
(5) Reports associated with trivalent chromium baths using a wetting agent.
Owners or operators with trivalent chromium baths using a wetting agent are not subject to paragraphs (1) through (3) of this subsection, but must instead submit the following reports:
(A) Sources currently using trivalent chrome. No later than 30 days after the effective date of this rule, the owner or operator shall submit a notification of compliance status that contains:
1. The name and address of each source subject to this paragraph;
2. A statement that a trivalent chromium process that incorporates a wetting agent will be used to comply with these requirements; and
3. The list of bath components that comprise the trivalent chromium bath, with the wetting agent clearly identified.
(B) Sources changing to trivalent chrome. Within 30 days of a change to the trivalent chromium electroplating process, a report that includes:
1. A description of the manner in which the process has been changed and the emission limitation, if any, now applicable to the source; and
2. The notification and reporting requirements of paragraphs (1), (2), and (3) of this subsection, if the source complies with the emission limitation option, or paragraph (5) of this subsection, if the source uses a wetting agent to comply. The report shall be submitted in accordance with the schedules identified in those paragraphs.
(6) Adjustments to the timeline for submittal and format of reports. A permitting agency may adjust the timeline for submittal of periodic reports, allow consolidation of multiple reports into a single report, establish a common schedule for submittal or reports, or accept reports prepared to comply with other State or local requirements. Prior to allowing an adjustment, the permitting agency must find that the adjustment will provide the same information and will not alter the overall frequency of reporting.
(j) New and Modified Sources.
(1) Notification of Construction Reports. After the effective date of this rule no person may construct or modify a source, such that it becomes a source subject to this section, without submitting a notification of construction or modification to the permitting agency and receiving approval in advance to construct or modify the source. The contents of the Notification of Construction Report is contained in Appendix 4.
(2) New Source Review Rules. In lieu of complying with the requirements in paragraph (j)(1) of this subsection, a facility may fulfill these requirements by complying with the permitting agency's new source review rule or policy, provided similar information is obtained.
(k) Procedure for Establishing Alternative Requirements.
(1) Request Approval of an Alternative Requirement. Any person may request approval of an alternative requirement. The person seeking such approval shall submit the proposed alternative requirement to the permitting agency for approval. The request must include the proposed alternative requirement, the reason for requesting the alternative requirement, and information demonstrating that the criteria for approval identified in Table (k)(1) is met.
(2) Approval of an Alternative Requirement. A permitting agency may approve an alternative requirement if it determines that application of the alternative requirement meets the criteria for approval identified in Table (k)(1), and the permitting agency has received concurrence by the U.S. EPA where concurrence is required.
(3) Concurrence for an Alternative Requirement. For those requirements identified in Table (k)(1) as requiring concurrence by the U.S. EPA, the permitting agency shall submit the alternative requirement to the concurring agency prior to final action by the permitting agency.
(4) Reports of Approved Alternative Requirements to U.S. EPA. The permitting agency shall provide the U.S. EPA with copies of all approved alternative requirements. The information shall be provided at a mutually agreed upon frequency.
(5) Approval Criteria. Nothing in this section prohibits the permitting agency from establishing approval criteria more stringent that required in Table (k)(1).
(6) Alternatives Approved by U.S. EPA. Waivers obtained from U.S. EPA prior to the effective date of this regulation shall remain in effect.
