CFR /  Title 40  /  Part 63  /  Sec. 63.656 Implementation and enforcement.

(a) This subpart can be implemented and enforced by the U.S. EPA, or a delegated authority such as the applicable State, local, or Tribal agency. If the U.S. EPA Administrator has delegated authority to a State, local, or Tribal agency, then that agency, in addition to the U.S. EPA, has the authority to implement and enforce this subpart. Contact the applicable U.S. EPA Regional Office to find out if implementation and enforcement of this subpart is delegated to a State, local, or Tribal agency.

(b) In delegating implementation and enforcement authority of this subpart to a State, local, or Tribal agency under subpart E of this part, the authorities contained in paragraph (c) of this section are retained by the Administrator of U.S. EPA and cannot be transferred to the State, local, or Tribal agency.

(c) The authorities that cannot be delegated to State, local, or Tribal agencies are as specified in paragraphs (c)(1) through (4) of this section.

(1) Approval of alternatives to the requirements in Sec. Sec. 63.640, 63.642(g) through (l), 63.643, 63.646 through 63.652, and 63.654. Where these standards reference another subpart, the cited provisions will be delegated according to the delegation provisions of the referenced subpart. Where these standards reference another subpart and modify the requirements, the requirements shall be modified as described in this subpart. Delegation of the modified requirements will also occur according to the delegation provisions of the referenced subpart.

(2) Approval of major alternatives to test methods under Sec. 63.7(e)(2)(ii) and (f), as defined in Sec. 63.90, and as required in this subpart.

(3) Approval of major alternatives to monitoring under Sec. 63.8(f), as defined in Sec. 63.90, and as required in this subpart.

(4) Approval of major alternatives to recordkeeping and reporting under Sec. 63.10(f), as defined in Sec. 63.90, and as required in this subpart. [68 FR 37351, June 23, 2003. Redesignated and amended at 74 FR 55686, 55688, Oct. 28, 2009] Sec. Sec. 63.657-63.679 [Reserved]

immediately downstream of the firebox before any substantial heat

exchange is encountered.\c\ ``Continuous records'' is defined in Sec. 63.641.\d\ NCS = Notification of Compliance Status Report described in Sec.

63.655.\e\ The daily average is the average of all recorded parameter values

for the operating day. If all recorded values during an operating day

are within the range established in the NCS or operating permit, a

statement to this effect can be recorded instead of the daily average.\f\ When a period of excess emission is caused by insufficient

monitoring data, as described in Sec. 63.655(g)(6)(i)(C) or (D), the

duration of the period when monitoring data were not collected shall

be included in the Periodic Report.\g\ PR = Periodic Reports described in Sec. 63.655(g).\h\ No monitoring is required for boilers and process heaters with a

design heat capacity =44 megawatts or for boilers and

process heaters where all vent streams are introduced into the flame

zone. No recordkeeping or reporting associated with monitoring is

required for such boilers and process heaters.\i\ Process vents that are routed to refinery fuel gas systems are not

regulated under this subpart. No monitoring, recordkeeping, or

reporting is required for boilers and process heaters that combust

refinery fuel gas. [60 FR 43260, Aug. 18, 1995, as amended at 61 FR 29881, 29882, June 12, 1996; 63 FR 44142, 44143, Aug. 18, 1998; 74 FR 55688, Oct. 28, 2009; 75 FR 37731, June 30, 2010] Subpart DD_National Emission Standards for Hazardous Air Pollutants from
