Code of Federal Regulations Title 40. Protection of Environment 40 CFR Pt. 63, Subpt. UUUUU, Tbl. 7 Table 7 to Subpart UUUUU of Part 63—Demonstrating Continuous Compliance

1. CEMS to measure filterable PM, SO₂, HCl, HF, or Hg emissions, or using a sorbent trap monitoring system to measure Hg

Calculating the 30- (or 90-) boiler operating day rolling arithmetic average emissions rate in units of the applicable emissions standard basis at the end of each boiler operating day using all of the quality assured hourly average CEMS or sorbent trap data for the previous 30- (or 90-) boiler operating days, excluding data recorded during periods of startup or shutdown.

2. PM CPMS to measure compliance with a parametric operating limit

Calculating the 30- (or 90-) boiler operating day rolling arithmetic average of all of the quality assured hourly average PM CPMS output data (e.g., milliamps, PM concentration, raw data signal) collected for all operating hours for the previous 30- (or 90-) boiler operating days, excluding data recorded during periods of startup or shutdown.

3. Site-specific monitoring using CMS for liquid oil-fired EGUs for HCl and HF emission limit monitoring

If applicable, by conducting the monitoring in accordance with an approved site-specific monitoring plan.

4. Quarterly performance testing for coal-fired, solid oil derived fired, or liquid oil-fired EGUs to measure compliance with one or more non-PM (or its alternative emission limits) applicable emissions limit in Table 1 or 2, or PM (or its alternative emission limits) applicable emissions limit in Table 2

Calculating the results of the testing in units of the applicable emissions standard.

5. Conducting periodic performance tune-ups of your EGU(s)

Conducting periodic performance tune-ups of your EGU(s), as specified in § 63.10021(e).

6. Work practice standards for coal-fired, liquid oil-fired, or solid oil-derived fuel-fired EGUs during startup

Operating in accordance with Table 3.

7. Work practice standards for coal-fired, liquid oil-fired, or solid oil-derived fuel-fired EGUs during shutdown

Operating in accordance with Table 3.
