40 CFR 145.11 - Requirements for permitting.
(a) All State programs under this part must have legal authority to implement each of the following provisions and must be administered in conformance with each; except that States are not precluded from omitting or modifying any provisions to impose more stringent requirements.
(1) Section 144.5(b)-(Confidential information);
(2) Section 144.6 - (Classification of injection wells);
(3) Section 144.7 - (Identification of underground sources of drinking water and exempted aquifers);
(4) Section 144.8 - (Noncompliance reporting);
(5) Section 144.11 - (Prohibition of unauthorized injection);
(7) Section 144.13 - (Elimination of Class IV wells);
(9) Sections 144.21-144.26 - (Authorization by rule);
(10) Section 144.31 - (Application for a permit);
(11) Section 144.32 - (Signatories);
(12) Section 144.33 - (Area Permits);
(13) Section 144.34 - (Emergency permits);
(14) Section 144.35 - (Effect of permit);
(15) Section 144.36 - (Duration);
(16) Section 144.38 - (Permit transfer);
(17) Section 144.39 - (Permit modification);
(18) Section 144.40 - (Permit termination);
(21) Section 144.53(a) - (Schedule of compliance);
(22) Section 144.54 - (Monitoring requirements);
(23) Section 144.55 - (Corrective Action);
(24) Section 124.3(a) - (Application for a permit);
(27) Section 124.8 - (Fact sheets);
(29) Section 124.11 - (Public comments and requests for hearings);
(30) Section 124.12(a) - (Public hearings);
(32) Section 144.88 - (What are the additional requirements?); and
(1) States need not implement provisions identical to the provisions listed in paragraphs (a)(1) through (a)(32) of this section. Implemented provisions must, however, establish requirements at least as stringent as the corresponding listed provisions. While States may impose more stringent requirements, they may not make one requirement more lenient as a tradeoff for making another requirement more stringent; for example, by requiring that public hearings be held prior to issuing any permit while reducing the amount of advance notice of such a hearing.
(2) State programs may, if they have adequate legal authority, implement any of the provisions of parts 144 and 124. See, for example § 144.37(d) (continuation of permits) and § 124.4 (consolidation of permit processing).
