For the following pollutants You must meet the following emission limits a Using the following averaging times And determine compliance by the following methods

1. Organics

Dioxins/Furans (total mass basis) 13 nanograms per dry standard cubic meter 3-run average (minimum run duration is 4 hours) Stack test.

2. Metals:

Cadmium 0.020 milligrams per dry standard cubic meter 3-run average (run duration specified in test method) Stack test.

Lead 0.20 milligrams per dry standard cubic meter 3-run average (run duration specified in test method) Stack test.

Mercury 0.080 milligrams per dry standard cubic meter or 85 percent reduction of potential mercury emissions 3-run average (run duration specified in test method) Stack test.

Opacity 10 percent Thirty 6-minute averages Stack test.

Particulate Matter 24 milligrams per dry standard cubic meter 3-run average (run duration specified in test method) Stack test.

3. Acid Gases:

Hydrogen Chloride 25 parts per million by dry volume or 95 percent reduction of potential hydrogen chloride emissions 3-run average (minimum run duration is 1 hour) Stack test

Nitrogen Oxides (Class I units) b 150 (180 for 1st year of operation) parts per million by dry volume 24-hour daily block arithmetic average concentration Continuous emission monitoring system.

Nitrogen Oxides (Class II units) c 500 parts per million by dry volume See footnote d See footnote d

Sulfur Dioxide 30 parts per million by dry volume or 80 percent reduction of potential sulfur dioxide emissions 24-hour daily block geometric average concentration or percent reduction Continuous monitoring emission system.

4. Other:

Fugitive Ash Visible emissions for no more than 5 percent of hourly observation period Three 1-hour observation periods Visible emission test.

a All emission limits (except for opacity) are measured at 7 percent oxygen.

b Class I units mean small municipal waste combustion units subject to this subpart that are located at municipal waste combustion plants with an aggregate plant combustion capacity more than 250 tons per day of municipal solid waste. See § 60.1465 for definitions.

c Class II units mean small municipal waste combustion units subject to this subpart that are located at municipal waste combustion plants with an aggregate plant combustion capacity no more than 250 tons per day of municipal solid waste. See § 60.1465 for definitions.

d No monitoring, testing, recordkeeping, or reporting is required to demonstrate compliance with the nitrogen oxides limit for Class II units.
