1. The owner or operator shall develop, in consultation with the department, a written site-specific monitoring plan. The site-specific monitoring plan shall be submitted to the department as part of the OM&M plan. The site-specific monitoring plan shall contain sufficient procedures to ensure continuing compliance with all applicable emission limits and shall demonstrate, based on documented test results, the relationship between emissions of PM, HCl and D&F and the proposed monitoring parameters for each pollutant. Test data shall establish the highest level of PM, HCl and D&F that will be emitted from the furnace. This emission level may be determined by conducting performance tests and monitoring operating parameters while charging the furnace with feed or charge materials containing the highest anticipated levels of oils and coatings and fluxing at the highest anticipated rate. If the department determines that any revisions of the site-specific monitoring plan are necessary to meet the requirements of this subchapter, the owner or operator shall promptly make all necessary revisions and resubmit the revised plan to the department.
NR 463.15(15)(a)2.
2. The site-specific monitoring plan shall contain all of the following as applicable:

NR 463.13 (9) (c) shall include requirements that the owner or operator record the type of feed or charge, such as ingot, thermally dried chips, dried scrap, or other, for each operating cycle or time period used in the performance test, and that the owner or operator submit a certification of compliance with the applicable operational standard for clean charge materials in
s. NR 463.14 (14) (c) for each 6-month reporting period. Each certification shall contain the information in
s. NR 463.18 (2) (b) 4.
NR 463.15(15)(a)2.d.

ch. NR 460.
NR 463.15(15)(a)2.e.
e. If a continuous opacity monitoring system is included in a site-specific monitoring plan, the plan shall include provisions for the installation, operation and maintenance of the system to provide quality-assured measurements in accordance with all applicable requirements of this subchapter.
NR 463.15(15)(a)2.f.

Test data shall establish the highest level of PM, HCl and D&F that will be emitted from the furnace. Subject to department approval of the OM&M plan, this may be determined by conducting performance tests and monitoring operating parameters while charging the furnace with feed or charge materials containing the highest anticipated levels of oils and coatings and fluxing at the highest anticipated rate.

NR 463.15(17)(c)
(c) Operating, monitoring, recordkeeping and reporting requirements to ensure that no scrap with a contaminant level higher than that used in the performance test is charged to the furnace.

subds. 1. to
3.:
NR 463.15(23)(c)1.
1. Data or information justifying the request, such as the technical or economic infeasibility, or the impracticality of using the required approach.
NR 463.15(23)(c)2.
2. A description of the proposed alternative monitoring requirements, including the operating parameters to be monitored, the monitoring approach and technique, and how the limit is to be calculated.
NR 463.15(23)(c)3.
3. Data and information documenting that the alternative monitoring requirements would provide equivalent or better assurance of compliance with the relevant emission standards.
NR 463.15(23)(d)
(d) The department may not approve an alternate monitoring application unless it would provide equivalent or better assurance of compliance with the relevant emission standards. Before disapproving any alternate monitoring application, the department shall provide both of the following:
NR 463.15(23)(d)1.
1. Notice of the information and findings upon which the intended disapproval is based.
NR 463.15(23)(d)2.
2. Notice of opportunity for the owner or operator to present additional supporting information before final action is taken on the application. This notice shall specify how much additional time is allowed for the owner or operator to provide additional supporting information.
NR 463.15(23)(e)
(e) The owner or operator is responsible for submitting any supporting information in a timely manner to enable the department to consider the application prior to the performance test. Neither submittal of an application nor the department's failure to approve or disapprove the application relieves the owner or operator of the responsibility to comply with any provisions of this subchapter.
NR 463.15(23)(f)
(f) The department may decide at any time, on a case-by-case basis, that additional or alternative operating limits, or alternative approaches to establishing operating limits, are necessary to demonstrate compliance with the emission standards of this subchapter.
