NR 462.04(1)(c) (c) You may demonstrate compliance with any applicable emission limit using fuel analysis if the emission rate calculated according to s. NR 462.05 (7) (d) is less than the applicable emission limit. Otherwise, you shall demonstrate compliance using performance testing.

NR 462.04(1)(d) (d) If you demonstrate compliance with any applicable emission limit through performance testing, you shall develop a site-specific monitoring plan according to the requirements in subds. 1. to 4. This requirement also applies to you if you petition the EPA administrator for alternative monitoring parameters under 40 CFR 63.8(f).

You shall submit this site-specific monitoring plan at least 60 days before your initial performance evaluation of your CMS. The plan shall include all of the following:

NR 462.04(1)(d)1.a. a. Installation of the CMS sampling probe or other interface at a measurement location relative to each affected process unit such that the measurement is representative of control of the exhaust emissions, such as on or downstream of the last control device.

NR 462.04(1)(d)1.b. b. Performance and equipment specifications for the sample interface, the pollutant concentration or parametric signal analyzer and the data collection and reduction systems.

NR 462.04(1)(d)1.c. c. Performance evaluation procedures and acceptance criteria, such as calibrations.

NR 462.04(1)(d)2. 2. In your site-specific monitoring plan you shall also address subd. 2. a. to c.

NR 462.04(1)(d)3. 3. You shall conduct a performance evaluation of each CMS in accordance with your site-specific monitoring plan.

NR 462.04(1)(d)4. 4. You shall operate and maintain the CMS in continuous operation according to the site-specific monitoring plan.

NR 462.04(1)(e) (e) If you have an applicable emission limit or work practice standard, you shall develop and implement a written startup, shutdown and malfunction plan (SSMP) according to the provisions in s. NR 460.05 (4) (c).
