# §63.1952. When am I no longer required to comply with the requirements of this subpart if I own or operate a bioreactor?


If you own or operate a landfill that includes a bioreactor, you are no longer required to comply with the requirements of this subpart for the bioreactor provided you meet the conditions of either paragraph [(a)](#a) or [(b)](#b) of this section.

- (a) Your affected source meets the control system removal criteria in [§ 63.1950](/cfr/40/63.1950.md) or the bioreactor meets the criteria for a nonproductive area of the landfill in [§ 63.1962(a)(3)(ii)](/cfr/40/63.1962.md?p=a-3-ii).
- (b) The bioreactor portion of the landfill is a closed landfill as defined in [§ 63.1990](/cfr/40/63.1990.md), you have permanently ceased adding liquids to the bioreactor, and you have not added liquids to the bioreactor for at least 1 year. A closure report for the bioreactor must be submitted to the Administrator as provided in [§ 63.1981(g)](/cfr/40/63.1981.md?p=g).
