Sec. 65.4  Recordkeeping.

    (a) Maintaining notifications, records, and reports. Except as 
provided in paragraph (b) of this section, the owner or operator of each 
regulated source subject to this part shall keep copies of 
notifications, reports, and records required by this part for the length 
of time specified in the following, as applicable:
    (1) If an owner or operator is required to obtain or operate a 
regulated source under a title V permit, then all applicable 
notifications, reports, and records for that regulated source shall be 
maintained for at least 5 years, except for the records required in 
Sec. 65.47(b) for storage vessel capacity, Sec. 
65.104(e)(2) for valve and connector monitoring, and Sec. 
65.163(d)(1) for closed vent system design specifications.
    (2) If an owner or operator is not required to obtain or operate a

of the most recent 2 years shall be retained onsite or shall be 
accessible to an inspector while onsite. The records of the remaining 3 
years, where required, may be retained offsite.
    (2) For sources referenced to this part from 40 CFR part 63, subpart 
G or H, the most recent 6 months of records shall be retained on site or 
shall be accessible to an inspector while onsite from a central location

request. The remaining 4 and one-half years of records, where required, 
may be retained offsite.
    (3) Records specified in paragraph (c)(1) or (2) of this section may 
be maintained in hard copy or computer-readable form including, but not 
limited to, on paper, microfilm, computer, computer disk, magnetic tape,
