SUPPLEMENTARY INFORMATION: 

On October 22, 1919 {44: FR 60758) 

EPA published a Notice of Proposed 

Rulemaking for Chapter 4, California Air 

Quality Control Strategies, submitted on 

May 23. 1919 by the California Air 

Resources Board· [ARB) for inclusi(JJl in 

the California SIP. As stated in that 

notice EPA proposed to approve the 

Chapter since it is consistent with EPA 

requirements. . The October 22. 1979 notice invited 

publlc comments.on the proposed 

rulemaking. Comments were received 

from the South Coast Air Quality 

Management DistriCt (SCAQMD), San 

Diego Gas & Electric [SD~. and 

Southem Callfomia Edison Company 

(SCEC). 

Comment: All three commenters 

argued that the ARB does not have the 

authority to determine reasonably 

available control technology (RACT) 

since this authority was vested 

primarily with the District as a result of 

Senate Bill (SB) 815. Thus, they 

recommend that EPA not incorporate 

the model rule portion of Chapter 4lnto 

the SIP. 

Response: SB 815 places the primary 

responsibility for determining RACT in 

the public agency which has the primary 

responsibility for implementation of that 

control measure. However. SB 815 does 

not appear to p~clude the ARB from 

documenting those rules considered by 

the State agency to be "reasonably 

available" and placing these model rules 

as an informational part of the SIP. 

Comment: SCEC atated that the Clean 

Air Act (CAA) doea not require model 

rules and the model rules contained in 

Chapter 4 do not represent RACT. For 

these reasona SCEC requested that EPA 

not incorporate the model rules into the 

SIP. 

Response: The CAA and 40 CFR 51.10 

and 51.12 require the SIP to Identify a 

control strategy and alternative control 

strategies for attainment and 

maintenance of the national amblent air 

quality atandardJ. Chapter 4, Including

Under Section 110 of the Clean Air 

Act. as amended. and 40 CFR Part 51, 

the Administrator ia required to approve 

or disapprove revilloDI to the SIP. As 

discussed In the proposal notice and for 

the reasons described above, Chapter 4 

has been determined to be conalstent 

with the CAA. Therefore, EPA takes 

final action to approve and Incorporate 

Chapter 4 into the Callfornia SIP. 

EPA has determined that tbia action Ia 

"specialized" and therefore, not subject 

to the procedural: requiremenll of 

Executive Order 12044. 

The Air Resources Board has certified 

that the public hearing requirements of 

40 CFR 51.4 have been aatisfied.
