(b) No owner or operator of an affected facility shall cause to be discharged into the atmosphere from the stack of that affected facility any gases that exhibit greater than 10% opacity (six-minute rolling average) or equal to or greater than 30% at any time.(c) No small HMIWI which is located more than 50 miles from the boundary of the nearest Standard Metropolitan Statistical Area (defined in 40 CFR 60.31e, September 15, 1997, 60 FR 48348), and which burns less than 2,000 pounds per week of hospital waste and medical/infectious waste shall cause to be discharged into the atmosphere from that affected facility any gases that contain stack emissions in excess of the limits presented in Table II. The 2,000 lb/week limitation does not apply during performance tests. Table II |

(d) Large HMIWI with capacity greater than 2,000 lb/hr for continuous and 16,000 lb/day for batch shall complete an ambient impact analysis for; arsenic and compounds expressed as arsenic; beryllium and compounds expressed as beryllium; hexavalent chromium and compounds expressed as chromium; and nickel and compounds expressed as nickel. (1) Using available emission factors, the emissions from the facility shall be estimated and the analysis shall be conducted by performing dispersion modeling using the facility's exhaust characteristics. The analysis shall be conducted in accordance with the procedures stipulated in the Air Quality Modeling Guidelines.(2) The required analysis must show that predicted concentrations do not exceed the following applicable annual ambient concentrations. Table III |
Allowable Ambient Concentrations |
Pollutant | Units | Allowable Ambient Concentration |
Arsenic (As) | g/m3 | 2.3e-04 |
Beryllium (Be) | g/m3 | 4.2e-04 |
Hexavalent Chromium (Cr (+6)) | g/m3 | 8.3e-05 |
Nickel (Ni) | g/m3 | 3.3e-03 |
g/m3 = micrograms per cubic meter |
(3) Compliance shall be verified by stack sampling as described in Section VII of this Standard. Using the actual stack parameters and emission rates from the most recent source test and Department approved modeling techniques, the calculated maximum annual ambient concentrations shall not exceed the above levels. The modeling methodology shall be submitted with the source test plans required by Regulation Regulation 61-62.1, Section IV., Source Tests. The applicant shall submit a Modeling Protocol to the Department and receive approval prior to starting any modeling study.(e) Large HMIWI with capacity greater than 2,000 lb/hr for continuous and 16,000 lb/day for batch shall maintain a combustion efficiency of 99.9% or greater on an hourly basis. The combustion efficiency shall be calculated as follows: C. E. = [CO2] x 100 / [CO2]+[CO]
C. E. = Combustion efficiency
[CO2] = Concentration of carbon dioxide (ppmv corrected to 7% O2)
[CO] = Concentration of carbon monoxide (ppmv corrected to 7% O2)
Note: O2, CO2, and CO determined on a dry basis.
(f) Upon mutual agreement of an owner or operator of a HMIWI and the Department, an emission limit more restrictive than that otherwise specified in this Standard and/or an emission limit for any air contaminant discharged from the HMIWI that is not specified in this Standard may be established. Also, upon mutual agreement of the owner or operator of an affected source and the Department, operating hours, process flow rates, or any other operating parameter may be established as a binding limit for the affected source. Any items mutually agreed to shall be stated as a special condition for any permit or order concerning the source. Violation of this mutual agreement will be considered a violation and will be subject to appropriate enforcement.S.C. Code Regs. § 61-62.5.3.1.III
