Texas SIP: 30 TAC 115.950: Use of Emissions Credits for Compliance
Texas Chapter 115 - Control of Air Pollution from Volatile Organic Compounds
SUBCHAPTER J: ADMINISTRATIVE PROVISIONS
DIVISION 4: EMISSIONS TRADING,
§115.950. Use of Emissions Credits for Compliance. 5-68, TXd81
§115.950. Use of Emissions Credits for Compliance.
As adopted by TCEQ December 6, 2000 effective January 18, 2001 (5-68).
Approved by EPA September 6, 2006 (71 FR 52698) effective October 6, 2006 (TXd81).
(a) An owner or operator may meet the emission control requirements of this chapter, in whole or in part, by obtaining emission reduction credits (ERCs), mobile emission reduction credits (MERCs), discrete emission reduction credits (DERCs), or mobile discrete emission reduction credits (MDERCs) in accordance with this section and Chapter 101, Subchapter H, Division 1 of this title (relating to Emission Credit Banking and Trading) or Chapter 101, Subchapter H, Division 4 of this title (relating to Discrete Emission Reduction Banking and Trading). For the purposes of this section, the term "RC" refers to an ERC, MERC, DERC, or MDERC, whichever is applicable.
(b) Any lower volatile organic compound (VOC) emission specification established under this chapter for the unit or units using RCs shall require the user of the RCs to obtain additional RCs in accordance with Chapter 101, Subchapter H, Division 1 of this title or Chapter 101, Subchapter H, Division 4 of this title and/or otherwise reduce emissions prior to the effective date of such rule change. The owner or operator of the unit(s) currently using RCs shall calculate the necessary emission reductions per unit as follows.
Figure 30 TAC 115.950(b):
delta E = [LA x (ERold - ERnew) x -----]
delta E = the differential of emissions
LA = the maximum level of activity
ERold = the existing VOC emission rate for the affected unit in lb per unit of activity
ERnew = the new VOC emission rate for the affected unit in lb per unit of activity
d = (i) to calculate annual emission reductions, d = 365
(ii) to calculate emission reductions for the remainder of a control period, d = the number of days remaining in the control period
