Amanda-

Below is Diane McConkey's answer to your question about PSD. It confirms


what we discussed when you called this morning -- this rulemaking
concerns 

a class of chemicals already regulated under the Clean Air Act, 

Best-

Cindy

Subject:	Fw: Question from Amanda on PSD for our rules

Ross, Cindy -- If we haven't gotten back to Amanda yet on this, here is 

the answer, which you could forward to her:

I assume the question is whether the pre-charged appliance rule will 

subject new pollutants to regulation, with attendant consequences under 

the PSD program.  The HCFCs at issue in the draft pre-charged appliance 

rule are already subject to regulation under Title VI and our
implementing 

regulations.  The statutory class II phaseout applies to all class II 

substances, and we regulated those substances in our 1993 phaseout rule
by 

establishing a chemical-by-chemical phaseout schedule.  The PCA rule
would 

not regulate any previously unregulated HCFCs.  Similarly, although the 

2010 allocation rule expands the coverage of the allowance system, the 

HCFCs it regulates are already subject to the chemical-by-chemical 

phaseout schedule established in our 1993 rule.
