Plans that use the collection services of nonprofit charitable organizations that qualify for a taxation exemption under section 501(c)(3) of the Internal Revenue Code of 1986 (26 U.S.C. Sec. 501(c)(3)) that are primarily engaged in the business of reuse and resale must be given an additional five percent credit to be applied toward a plan's equivalent share for pounds that are received for recycling from those organizations. Ecology may adjust the percentage of credit annually.
