Current through Register Vol. 48, No. 6, June 28, 2024
(a) On
				  and after the date on which the initial performance test is completed or is
				  required to be completed as per Section VII of this Standard, whichever date
				  comes first, no owner or operator of an affected facility 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 I below.

(b) No owner or operator of an affected

				  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

(d) Large HMIWI with capacity greater than

				  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.

(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.
