### 4, 

### CaliforniaAir 

### Quality ControlStrategies, 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 CallfomiaEdison Company (SCEC).



### Comment: All three commenters argued that the ARB does nothave 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 ofChapter4lnto the SIP.



### Response: SB 815 places the primary responsibility for determining RACT in the public agency which has the primary responsibility for implementation ofthat 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 ofthe SIP.



### Comment: SCEC atated that the Clean AirAct (CAA) doea not require model rules andthe model rules contained in Chapter4 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 ofthe national amblent air quality atandardJ. Chapter4, Including the model rulea.ls consistent with these requirements. Approval ofChapter C, which Includes the model roles. doea not constitute agreement by
