# §146.9. Criteria for establishing permitting priorities.


In determining priorities for setting times for owners or operators to submit applications for authorization to inject under the procedures of § [144.31 (a)](/cfr/40/144.31.md?p=a), [(c)](/cfr/40/144.31.md?p=c), [(g)](/cfr/40/144.31.md?p=g) or [§ 144.22(f)](/cfr/40/144.22.md?p=f), the Director shall base these priorities upon consideration of the following factors:

- (a) Injection wells known or suspected to be contaminating underground sources of drinking water;
- (b) Injection wells known to be injecting fluids containing hazardous contaminants;
- (c) Likelihood of contamination of underground sources of drinking water;
- (d) Potentially affected population;
- (e) Injection wells violating existing State requirements;
- (f) Coordination with the issuance of permits required by other State or Federal permit programs;
- (g) Age and depth of the injection well; and
- (h) **Expiration dates of existing State permits, if any.**
