**Background:**

1.  **Rule Evaluation**

> South Coast AQMD is amending Rule 102 to add and modify several
> definitions.

a.  The term 'agricultural permit unit' is added to identify each
    individual piece of equipment or operation that will require Permits
    to Construct and Permits to Operate at agricultural facilities. This
    definition is similar to that used to identify equipment requiring
    an AQMD permit at other stationary sources except that it also
    includes confined animal facilities and allows all orchard wind
    machines at a source operated under limited conditions to be a
    single permit unit. Although confined animal facilities may require
    a permit, the production of crops in and of itself does not require
    a permit and therefore is not defined as an agricultural permit
    unit.

b.  The term 'agricultural source' is added, to be consistent with that
    same term defined in the text of SB 700 to include all the sources
    of air emissions on contiguous property under the same ownership or
    control that are used in the production of crops or the raising of
    fowl or animals.

c.  The term 'clean air solvent certificate' is added to specify a
    product or class of products that meets the criteria for a Clean Air
    Solvent.

d.  The term 'confined animal facility (CAF)' is added to be consistent
    with SB700, with a deminimus level based on the number of animals or
    fowl at a facility that is the same as the exemption level in Rule
    1127, based upon the number of animals at a dairy farm.

e.  The term 'hazardous air pollutant' has been added to be consistent
    with federal requirements.

f.  The term 'orchard heater' has been modified to clarify that these
    devices must meet the requirements of the California Health and
    Safety Code.

g.  The term 'orchard wind machine' is defined to clarify that for air
    quality purposes the concern is only for those powered by internal
    combustion engines.

2.  **Strengthening Areas**

> This rule's revised definitions improves the SIP by clarifying terms
> used in other requirements.

3.  **Net Effect on Emissions**

> This rule does not affect emissions, but serves to clarify district
> rules.

4\. **Recommended Action**

The above rule was evaluated against the document entitled, "Issues
Relating to VOC regulation Cutpoint, Deficiencies and Deviation:
Clarification to Appendix D of November 24, 1987, Federal Register," May
25, 1988 (the "Blue Book") and the Clean Air Act Amendments (CAAA of
1990).

EPA recommends approval of South Coast AQMD Rule 102.
