# §60.5560. What records must I maintain?

- (a) You must maintain records of the information you used to demonstrate compliance with this subpart as specified in § [60.7(b)](/cfr/40/60.7.md?p=b) and [(f)](/cfr/40/60.7.md?p=f).
- (b)
  - (1) For affected EGUs subject to the Acid Rain Program, you must follow the applicable recordkeeping requirements and maintain records as required under [subpart F of part 75](/cfr/40/part75-subpartF.md) of this chapter.
  - (2) For affected EGUs that are not subject to the Acid Rain Program, you must also follow the recordkeeping requirements and maintain records as required under [subpart F of part 75](/cfr/40/part75-subpartF.md) of this chapter, to the extent that those records provide applicable data for the compliance determinations required under this subpart. Regardless of the prior sentence, at a minimum, the following records must be kept, as applicable to the types of continuous monitoring systems used to demonstrate compliance under this subpart:
    - (i) Monitoring plan records under § [75.53(g)](/cfr/40/75.53.md?p=g) and [(h)](/cfr/40/75.53.md?p=h) of this chapter;
    - (ii) Operating parameter records under [§ 75.57(b)(1) through (4)](/cfr/40/75.57.md?p=b-1..b-4) of this chapter;
    - (iii) The records under [§ 75.57(c)(2)](/cfr/40/75.57.md?p=c-2) of this chapter, for stack gas volumetric flow rate;
    - (iv) The records under [§ 75.57(c)(3)](/cfr/40/75.57.md?p=c-3) of this chapter for continuous moisture monitoring systems;
    - (v) The records under [§ 75.57(e)(1)](/cfr/40/75.57.md?p=e-1) of this chapter, except for paragraph (e)(1)(x), for CO2 concentration monitoring systems or O2 monitors used to calculate CO2 concentration;
    - (vi) The records under [§ 75.58(c)(1)](/cfr/40/75.58.md?p=c-1) of this chapter, specifically paragraphs (c)(1)(i), (ii), and [(viii) through (xiv)](#b-c-1-viii..b-c-1-xiv), for oil flow meters;
    - (vii) The records under [§ 75.58(c)(4)](/cfr/40/75.58.md?p=c-4) of this chapter, specifically paragraphs (c)(4)(i), (ii), (iv), (v), and [(vii) through (xi)](#b-c-4-vii..b-c-4-xi), for gas flow meters;
    - (viii) The quality-assurance records under [§ 75.59(a)](/cfr/40/75.59.md?p=a) of this chapter, specifically paragraphs [(a)(1) through (12)](#a-1..a-12) and (15), for CEMS;
    - (ix) The quality-assurance records under [§ 75.59(a)](/cfr/40/75.59.md?p=a) of this chapter, specifically [paragraphs (b)(1) through (4)](#b-1..b-4), for fuel flow meters; and
    - (x) Records of data acquisition and handling system (DAHS) verification under [§ 75.59(e)](/cfr/40/75.59.md?p=e) of this chapter.
- (c) You must keep records of the calculations you performed to determine the hourly and total CO2 mass emissions (tons) for:
  - (1) Each operating month (for all affected EGUs); and
  - (2) **Each compliance period, including, each 12-operating-month compliance period.**
- (d) Consistent with [§ 60.5520](/cfr/40/60.5520.md), you must keep records of the applicable data recorded and calculations performed that you used to determine your affected EGU's gross or net energy output for each operating month.
- (e) You must keep records of the calculations you performed to determine the percentage of valid CO2 mass emission rates in each compliance period.
- (f) You must keep records of the calculations you performed to assess compliance with each applicable CO2 mass emissions standard in Table 1 or 2 of this subpart.
- (g) You must keep records of the calculations you performed to determine any site-specific carbon-based F-factors you used in the emissions calculations (if applicable).
- (h) For stationary combustion turbines, you must keep records of electric sales to determine the applicable subcategory.
- (i) You must keep the records listed in [paragraphs (i)(1) through (3)](#i-1..i-3) of this section to demonstrate that your affected facility operated during a system emergency.
  - (1) Documentation that the system emergency to which the affected EGU was responding was in effect from the entity issuing the alert, and documentation of the exact duration of the event;
  - (2) Documentation from the entity issuing the alert that the system emergency included the affected source/region where the affected facility was located, and
  - (3) Documentation that the affected facility was instructed to increase output beyond the planned day-ahead or other near-term expected output and/or was asked to remain in operation outside its scheduled dispatch during emergency conditions from a Reliability Coordinator, Balancing Authority, or Independent System Operator/Regional Transmission Organization.
