          Subpart A--Emission Inventory Reporting Requirements
 
Sec. 51.20  What are the emission thresholds that separate point and area 
sources?

    (a) All anthropogenic stationary sources must be included in your 
inventory as either point or area sources.
    (b) See Table 1 of Appendix A to this subpart for minimum reporting 
thresholds on point sources.
    (c) Your State has two alternatives to the point source reporting 
thresholds in paragraph (b) of this section:
    (1) You may choose to define point sources by the definition of a 
major source used under CAA Title V, see 40 CFR 70.2.
    (2) If your State has lower emission reporting thresholds for point 
sources than paragraph (b) of this section, then you may use these in 
reporting your emissions to EPA.
    (d) All stationary sources that have actual emissions lower than the 
thresholds specified in paragraphs (b) and (c) of this section, should 
be reported as area sources.
