(ii) If total SO2 emissions during a control period in a given year from the Texas SO2 Trading Program units at a Texas SO2 Trading Program source are in excess of the Texas SO2 Trading Program emissions limitation set forth in paragraph (c)(1)(i) of this section, then:

(A) The owners and operators of the source and each Texas SO2 Trading Program unit at the source shall hold the Texas SO2 Trading Program allowances required for deduction under §97.924(d); and

(B) The owners and operators of the source and each Texas SO2 Trading Program unit at the source shall pay any fine, penalty, or assessment or comply with any other remedy imposed, for the same violations, under the Clean Air Act, and each ton of such excess emissions and each day of such control period shall constitute a separate violation of this subpart and the Clean Air Act.

(6) Property right. A Texas SO2 Trading Program allowance does not constitute a property right.

(d) Title V permit requirements.

(1) No title V permit revision shall be required for any allocation, holding, deduction, or transfer of Texas SO2 Trading Program allowances in accordance with this subpart.

(2) A description of whether a unit is required to monitor and report SO2 emissions using a continuous emission monitoring system (under subpart B of part 75 of this chapter), an excepted monitoring system (under appendices D and E to part 75 of this chapter), a low mass emissions excepted monitoring methodology (under §75.19 of this chapter), or an alternative monitoring system (under subpart E of part 75 of this chapter) in accordance with §§97.930 through 97.935 may be added to, or changed in, a title V permit using minor permit modification procedures in accordance with §§70.7(e)(2) and 71.7(e)(1) of this chapter, provided that the requirements applicable to the described monitoring and reporting (as added or changed, respectively) are already incorporated in such permit. This paragraph explicitly provides that the addition of, or change to, a unit's description as described in the prior sentence is eligible for minor permit modification procedures in accordance with §§70.7(e)(2)(i)(B) and 71.7(e)(1)(i)(B) of this chapter.

(e) Additional recordkeeping and reporting requirements.

(1) Unless otherwise provided, the owners and operators of each Texas SO2 Trading Program source and each Texas SO2 Trading Program unit at the source shall keep on site at the source each of the following documents (in hardcopy or electronic format) for a period of 5 years from the date the document is created.

(iii) Copies of all reports, compliance certifications, and other submissions and all records made or required under, or to demonstrate compliance with the requirements of, the Texas SO2 Trading Program.

(2) The designated representative of a Texas SO2 Trading Program source and each Texas SO2 Trading Program unit at the source shall make all submissions required under the Texas SO2 Trading Program, except as provided in §97.918. This requirement does not change, create an exemption from, or otherwise affect the responsible official submission requirements under a title V operating permit program in parts 70 and 71 of this chapter.

(f) Liability.

(1) Any provision of the Texas SO2 Trading Program that applies to a Texas SO2 Trading Program source or the designated representative of a Texas SO2 Trading Program source shall also apply to the owners and operators of such source and of the Texas SO2 Trading Program units at the source.
