(j) All documentation produced as a result of the siting requirements of §§ 60.2894 and 60.2895.

(k) Records showing the names of OSWI unit operators who have completed review of the information in § 60.2910(a) as required by § 60.2910(b), including the date of the initial review and all subsequent annual reviews.

(l) Records showing the names of the OSWI unit operators who have completed the operator training requirements under § 60.2905, met the criteria for qualification under § 60.2907, and maintained or renewed their qualification under § 60.2908 or § 60.2909. Records must include documentation of training, the dates of the initial and refresher training, and the dates of their qualification and all subsequent renewals of such qualifications.

(m) For each qualified operator, the phone and/or pager number at which they can be reached during operating hours.

(n) Equipment vendor specifications and related operation and maintenance requirements for the incinerator, emission controls, and monitoring equipment.

(o) The information listed in § 60.2910(a).

(p) If you comply with the substitute means of compliance demonstration requirements in § 60.2929, you must keep the records specified in paragraphs (p)(1) through (4) of this section.

(1) Copy of the notification submitted to the Administrator that you intend to use the substitute means of compliance demonstration as required in § 60.2929(a)(1).

(2) Records of the data collected as required in § 60.2929(a)(2).

(3) Copy of the representative performance test used to demonstrate initial compliance; and

(4) Documentation of how the test in paragraph (p)(3) of this section is representative of the unit as required in § 60.2929(b)(2).

(q) If you comply with the continuous compliance requirements of § 60.2932(d), you must keep records of the following elements:
