Universal Citation: WI Admin Code § NR 462.04

Current through August 26, 2024

(1) WHAT ARE MY GENERAL REQUIREMENTS FOR COMPLYING WITH THIS CHAPTER?

(a) You shall be in compliance with the emission limits, including operating limits, and the work practice standards in this chapter at all times, except during periods of startup, shutdown and malfunction.

(b) You shall always operate and maintain your affected source, including air pollution control and monitoring equipment, according to the provisions in s. NR 460.05(4) (a) 1.

(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.

(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).

Note: The authority to approve alternative monitoring parameters is retained by the administrator and is not delegated to the department.

1. For each continuous monitoring system (CMS) required in this subsection, you shall develop and submit to the department for approval a site-specific monitoring plan that addresses subd. 1. a. to c. 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:

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.

b. Performance and equipment specifications for the sample interface, the pollutant concentration or parametric signal analyzer and the data collection and reduction systems.

c. Performance evaluation procedures and acceptance criteria, such as calibrations.

2. In your site-specific monitoring plan you shall also address subd. 2. a. to c.

a. Ongoing operation and maintenance procedures in accordance with the general requirements of s. NR 460.07(3) (a), (c) and (d) 2.

b. Ongoing data quality assurance procedures in accordance with the general requirements of s. NR 460.07(4).

c. Ongoing recordkeeping and reporting procedures in accordance with the general requirements of s. NR 460.09(3) (a) and (5) (a) and (b) 1.

3. You shall conduct a performance evaluation of each CMS in accordance with your site-specific monitoring plan.

4. You shall operate and maintain the CMS in continuous operation according to the site-specific monitoring plan.

(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).

(2) DO ANY BOILERS OR PROCESS HEATERS HAVE LIMITED REQUIREMENTS?

(a) New or reconstructed boilers and process heaters in the large liquid fuel subcategory or the limited use liquid fuel subcategory that burn only fossil fuels and other gases and do not burn any residual oil are subject to the emission limits and applicable work practice standards in Table 1 of this chapter. You are not required to conduct a performance test to demonstrate compliance with the emission limits. You are not required to set and maintain operating limits to demonstrate continuous compliance with the emission limits. However, you shall meet the requirements in subds. 1. and 2. and meet the CO work practice standard in Table 1 of this chapter.

1. To demonstrate initial compliance, you shall include a signed statement in the notification of compliance status report required in s. NR 462.07(1) (e) that indicates you burn only liquid fossil fuels other than residual oils, either alone or in combination with gaseous fuels.

2. To demonstrate continuous compliance with the applicable emission limits, you shall also keep records that demonstrate that you burn only liquid fossil fuels other than residual oils, either alone or in combination with gaseous fuels. You shall also include a signed statement in each semiannual compliance report required in s. NR 462.07(2) that indicates you burned only liquid fossil fuels other than residual oils, either alone or in combination with gaseous fuels, during the reporting period.

(b) The affected boilers and process heaters listed in subds. 1. to 3. are subject to only the initial notification requirements in s. NR 460.08(2). They are not subject to the emission limits, work practice standards, performance testing, monitoring, SSM plans, site-specific monitoring plans, recordkeeping and reporting requirements of this chapter or any other requirements in ch. NR 460.

1. Existing large and limited use gaseous fuel units.

2. Existing large and limited use liquid fuel units.

3. New or reconstructed small liquid fuel units that burn only gaseous fuels or distillate oil. New or reconstructed small liquid fuel boilers and process heaters that commence burning any other type of liquid fuel shall comply with all applicable requirements of this chapter and ch. NR 460 upon commencing the burning of the other type of liquid fuel.

(c) The affected boilers and process heaters listed in subds. 1. to 4. are not subject to the initial notification requirements in s. NR 460.08(2) and are not subject to any requirements in this chapter or in ch. NR 460. They are not subject to the emission limits, work practice standards, performance testing, monitoring, SSM plans, site-specific monitoring plans, recordkeeping and reporting requirements of this chapter or any other requirements in ch. NR 460.

1. Existing small solid fuel boilers and process heaters.

2. Existing small liquid fuel boilers and process heaters.

3. Existing small gaseous fuel boilers and process heaters.

4. New or reconstructed small gaseous fuel units.

(3) WHAT ARE THE HEALTH-BASED COMPLIANCE ALTERNATIVES FOR THE HYDROGEN CHLORIDE AND TOTAL SELECTED METALS STANDARDS?

(a) As an alternative to the requirement to demonstrate compliance with the HCl emission limit in Table 1 of this chapter, you may demonstrate eligibility for the health-based compliance alternative for HCl emissions under the procedures prescribed in 40 CFR part 63, subpart DDDDD, Appendix A, incorporated by reference in s. NR 484.04(24m).

(b) As an alternative to the requirement to demonstrate compliance with the TSM emission limit in Table 1 of this chapter based on the sum of emissions for the 8 selected metals, you may demonstrate eligibility for the health-based alternative for manganese emissions under the procedures prescribed in 40 CFR part 63, subpart DDDDD, Appendix A, incorporated by reference in s. NR 484.04(24m) and comply with the TSM emission standards in Table 1 based on the sum of emissions for 7 selected metals, by excluding manganese emissions from the summation of TSM emissions.

(4) WHAT PARTS OF THE GENERAL PROVISIONS APPLY TO ME? Appendix DDDDD of ch. NR 460 shows which parts of the general provisions in ch. NR 460 apply to you.
