Status message

There are 7 Updates appearing in the Federal Register for 40 CFR 63. View below or at eCFR (GPOAccess)
§ 63.8687 What performance tests, design evaluations, and other procedures must I use?
(a) You must conduct each performance test in Table 3 to this subpart that applies to you.
(b) Each performance test must be conducted under normal operating conditions and under the conditions specified in Table 3 to this subpart.
(c) You may not conduct performance tests during periods of startup, shutdown, or malfunction, as specified in § 63.7(e)(1).
(d) Except for opacity and visible emission observations, you must conduct three separate test runs for each performance test required in this section, as specified in § 63.7(e)(3). Each test run must last at least 1 hour.
(e) You must use the following equations to determine compliance with the emission limitations.
(1) To determine compliance with the particulate matter mass emission rate, you must use Equations 1 and 2 of this section as follows:
Where:
E = Particulate matter emission rate, kilograms of particulate matter per megagram of roofing product manufactured.
MPM = Particulate matter mass emission rate, kilograms per hour, determined using Equation 2.
P = The asphalt roofing product manufacturing rate during the emissions sampling period, including any material trimmed from the final product, megagram per hour.
Where:
MPM = Particulate matter mass emission rate, kilograms per hour.
C = Concentration of particulate matter on a dry basis, grams per dry standard cubic meter (g/dscm), as measured by the test method specified in Table 3 to this subpart.
Q = Vent gas stream flow rate (dry standard cubic meters per minute) at a temperature of 20 °C as measured by the test method specified in Table 3 to this subpart.
K = Unit conversion constant (0.06 minute-kilogram/hour-gram).
(2) To determine compliance with the total hydrocarbon percent reduction standard, you must use Equations 3 and 4 of this section as follows:
Where:
RE = Emission reduction efficiency, percent.
MTHCi = Mass flow rate of total hydrocarbons entering the control device, kilograms per hour, determined using Equation 4.
MTHCo = Mass flow rate of total hydrocarbons exiting the control device, kilograms per hour, determined using Equation 4.
Where:
MTHC = Total hydrocarbon mass flow rate, kilograms per hour.
C = Concentration of total hydrocarbons on a dry basis, parts per million by volume (ppmv), as measured by the test method specified in Table 3 to this subpart.
Q = Vent gas stream flow rate (dscm/minute) at a temperature of 20 °C as measured by the test method specified in Table 3 to this subpart.
K = Unit conversion constant (1.10E-04 (ppmv) −1 (kilogram/dscm)(minute/hour)).
(3) To determine compliance with the combustion efficiency standard, you must use Equation 5 of this section as follows:
Where:
CE = Combustion efficiency, percent.
CO = Carbon monoxide concentration at the combustion device outlet, parts per million by volume (dry), as measured by the test method specified in Table 3 to this subpart.
CO2 = Carbon dioxide concentration at the combustion device outlet, parts per million by volume (dry), as measured by the test method specified in Table 3 to this subpart.
THC = Total hydrocarbon concentration at the combustion device outlet, parts per million by volume (dry), as measured by the test method specified in Table 3 to this subpart.
(4) To determine compliance with the total hydrocarbon destruction efficiency standard for a combustion device that does not use auxiliary fuel, you must use Equation 6 of this section as follows:
Where:
THC DE = THC destruction efficiency, percent.
CO = Carbon monoxide concentration at the combustion device outlet, parts per million by volume (dry), as measured by the test method specified in Table 3 to this subpart.
CO2 = Carbon dioxide concentration at the combustion device outlet, parts per million by volume (dry), as measured by the test method specified in Table 3 to this subpart.
THC = Total hydrocarbon concentration at the combustion device outlet, parts per million by volume (dry), as measured by the test method specified in Table 3 to this subpart.
