Discrete Emission Credit Program
The Discrete Emission Credit program allows participants to generate credits by creating temporary (i.e., discrete) emission reductions from stationary, area, and mobile sources. Reductions generated from stationary and area sources are known as Discrete Emission Reduction Credits (DERC) while reductions from mobile sources are known as Mobile DERCs (MDERC). This program encourages emission reductions and provides participants flexibility in complying with various federal and state air regulations. Participation is completely voluntary.
Program rules are listed under 30 TAC Chapter 101, Subchapter H, Division 4.
