2. (2) Eligible Renewable Energy Resources.

   1. (A) The electricity must be derived from one (1) of the following types of renewable energy resources or technologies, as defined in section 393.1025(5), RSMo:

      1. 1. Wind;
      2. 2. Solar thermal sources or solar photovoltaic cells and

panels;

1. 3. Dedicated crops grown for energy production—

herbaceous and woody crops that are harvested specifically for energy production in a sustainable manner;

1. 4. Cellulosic agricultural residues—organic matter re-

maining after the harvesting and processing of agricultural crops. They include—

1. A. Field residues–organic materials left on agricultural

lands after the crops have been harvested, such as stalks, stubble, leaves, and seed pods; and

1. B. Process residues–organic materials left after the crops

have been processed into a usable resource, such as husks, seeds, and roots;

1. 5. Plant residues—the residues of plants that would be

converted into energy, that otherwise would be waste material;

1. 6. Clean and untreated wood—non-hazardous wood 1) that

has not been chemically treated with chemical preservatives such as creosote, pentachlorophenol, or chromated copper arsenate; and 2) that does not contain resins, glues, laminates, paints, preservatives, or other treatments that would combust or off-gas, or mixed with any other material that would burn, melt, or create other residue aside from wood ash.

1. A. Eligible clean and untreated wood may include but is

not necessarily limited to the following sources:

1. (I) Forest-related resources, such as pre-commercial

thinnings waste, slash (tree tops, branches, bark, or other residue left on the ground after logging or other forestry operations), brush, shrubs, stumps, lumber ends, trimmings, yard waste, dead and downed forest products, and small diameter forest thinnings (twelve inches (12") in diameter or less);

1. (II) Non-chemically treated wood and paper manufac-

turing waste, such as bark, trim slabs, scrap, shavings, sawdust, sander dust, and pulverized scraps;

1. (III) Vegetation waste, such as landscape waste or

right-of-way trimmings;

1. (IV) Wood chips, pellets, or briquettes derived from

non-toxic and unadulterated wood wastes or woody energy crops;

1. (V) Municipal solid waste, construction and demoli-

tion waste, urban wood waste, and other similar sources only if wood wastes are segregated from other solid wastes or inorganic wastes; and

1. (VI) Other miscellaneous waste, such as waste pellets,

pallets, crates, dunnage, scrap wood, tree debris left after a natural catastrophe, and recycled paper fibers that are no longer suitable for recycled paper production.

1. B. Ineligible clean and untreated wood may include but

is not necessarily limited to the following sources:

1. (I) Post-consumer wastepaper;
2. (II) Wood from old growth forests (one hundred fifty

1. (150) years old or older);

   1. (III) Unsegregated solid waste; or
   2. (IV) Black liquor, unless used as an input consistent

with paragraph (2)(A)10. of this rule;

1. 7. Methane from landfills, wastewater treatment, or

agricultural operations. Agricultural operations are defined as 1) the growing or harvesting of aquatic plants or agricultural crops grown in soil; or 2) the raising of animals for the purpose of making a profit, providing a livelihood, or conducting agricultural research or instruction. Wastewater treatment is defined as physical, chemical, biological, and mechanical procedures applied to an industrial or municipal discharge or to any other sources of contaminated water to remove, reduce, or neutralize contaminants;

1. 8. Hydropower, not including pumped storage, that does

not require a new diversion or impoundment of water and that each generator has a nameplate rating of ten megawatts (10 MW) or less. If an improvement to an existing hydropower facility does not require a new diversion or impoundment of water and incrementally increases the nameplate rating of each generator, up to ten megawatts (10 MW) per generator, the improvement qualifies as an eligible renewable energy resource;

1. 9. Fuel cells using hydrogen produced by one (1) of the

above-named renewable energy resources. RECs based on generating electricity in fuel cells from hydrogen derived from an eligible energy resource are eligible for compliance purposes only to the extent that the energy used to generate the hydrogen did not create RECs;

1. 10. Products from thermal depolymerization or pyrolysis

of waste material. Waste materials are specifically segregated materials from a waste stream for the purpose of producing energy or that are capable of producing energy. Pyrolysis is a thermochemical process through which organic matters are decomposed at elevated temperatures in an oxygen-deficient atmosphere into useful energy forms. Thermal depolymerization is the thermal decomposition (hydrous pyrolysis process) of organic compounds heated to high temperatures in the presence of water resulting in liquid oil; or

1. 11. Other sources of energy, not including nuclear, that may

become available after November 4, 2008, and are certified as eligible renewable energy resources as provided in section (3) of this rule.

1. (3) Additions to Eligible Renewable Energy Resources.
