I. BackgroundA. Air Emission Sources

■ “Air contamination source or emission source: Any apparatus, contrivance or machine capable of causing emission of any air contaminant to the outdoor atmosphere, including any appurtenant exhaust system or air cleaning device. Where a process at an emission unit uses more than one apparatus, contrivance or machine in combination, the combination may be considered a single emission source.” [6 NYCRR 200.1(f)]

■ “Part 212 applies to process emission sources and/or emission points associated with a process operation, unless excepted … pursuant to §212-1.4…” [6 NYCRR 212-1.1(a)]

“Process Emission Source: Any apparatus, contrivance or machine, including any appurtenant exhaust system or air cleaning device capable of causing emissions of any air contaminant to the outdoor atmosphere from a process operation”.

“Process operation: Any industrial, institutional, commercial, agricultural or other activity, operation, manufacture or treatment in which chemical, biological and/or physical properties of the material or materials are changed, or in which the material(s) is conveyed or stored without changing the material(s) if the conveyance or storage system is equipped with a vent(s) and is non-mobile, and that emits air contaminants to the outdoor atmosphere. A process operationdoes not include an open fire, operation of a combustion installation, or incineration of refuse other than by-products or wastes from a process operation(s).”

■ Environmental ratings are determined by NYSDEC.■ Environmental ratings are generally based upon the toxicity classification in

DAR-1■ NYSDEC has the ability to increase the environmental rating if the ambient air

concentration is above the AGC and/or SGC value in DAR-1.■ Air dispersion modeling must be performed to demonstrate that the ambient air

concentration is below the AGC and/or SGC value in DAR-1.

Some emissions are “conditionally exempted” from Part 212.:■ “Conditional exemptions” in §212-1.4 include:

- “process emission sources subject to Subpart 228-1… or process emission sources exempt from Subpart 228-1 …, only with respect to emissions of VOCs that are not given an A rating”;

- “pharmaceutical and cosmetic manufacturing process operations subject to Part 233 of this Title and process operations exempt from Part 233 of this Title pursuant to Section 233.1(g), only with respect to emissions of VOCs that are not given an A rating”

■ Emissions that are “conditionally exempt” must be included in an air dispersion modeling analysis to demonstrate that the ambient impacts do not warrant an environmental rating of “A”.

greater that the Mass Emission Limit;

IV. Air Quality Impact Analysis Requirements

A. Air Dispersion Modeling Software Calculations using “Cavity Method” are no longer acceptable.

USEPA AERSCREEN Modeling Software (use current version) conservative estimation of air emission concentration each source modeled individually does not require submission/approval of an air dispersion modeling protocol

before results are submitted to NYSDEC

USEPA AERMOD Modeling Software (use current version) “ more-refined” estimation of air emission concentration each source modeled concurrently custom meteorological data sets provided by NYSDEC requires submission/approval of an air dispersion modeling protocol NOTE RE. AERMOD in “screen mode”: NYSDEC recently indicated that use

of the “screen mode” will now require the submission and approval of an air dispersion modeling protocol.

VI. Conclusions

Facility must address Part 212 applicability and compliance requirements when renewing or modifying the permit.

Evaluating and complying with Part 212 can be complicated.

Information to perform evaluation that may not be up-to-date (or available).

- current inventory of emission sources that are subject to permitting

- detailed emission rate calculations for all air contaminants

An air dispersion modeling analysis will most likely be required.

A strategic approach should be utilized to ensure that operational flexibility is not compromised.

Addressing Part 212 requirements could add costs and time that include:

- Emission inventory and calculations;

- Air dispersion modeling (including costs to develop/submit Air Dispersion Modeling Protocol);

- T-BACT or BACT Assessments; and

- Installation of emission control.
