7 utility districts are authorized to produce and distribute biodiesel,
8 ethanol, and ethanol blend fuels, including entering into crop
9 purchase contracts for a dedicated energy crop for the purpose of
10 generating electricity or producing biodiesel produced from
11 Washington feedstocks, cellulosic ethanol, and cellulosic ethanol
12 blend fuels for use in internal operations of the electric utility
13 and for sale or distribution.
14 (2) In addition to any other authority provided by law:
15 (a) Public utility districts are authorized to produce renewable
16 natural gas, green electrolytic hydrogen, and renewable hydrogen and
17 utilize the renewable natural gas, green electrolytic hydrogen, or
18 renewable hydrogen they produce for internal operations.
19 (b) Public utility districts may sell renewable natural gas,
20 green electrolytic hydrogen, or renewable hydrogen that is delivered
p. 1 SSB 5919.SL
1 into a gas transmission pipeline located in the state of Washington
2 or delivered in pressurized containers:
3 (i) At wholesale;
4 (ii) To an end-use customer; or
5 (iii) If delivered in a pressurized container, or if the end-use

7 electrolytic hydrogen, or renewable hydrogen through a pipeline, and
8 the end-use customer is an eligible purchaser of natural gas from
9 sellers other than the gas company from which that end-use customer
10 takes transportation service and:
11 (A) When the sale is made to an end-use customer in the state of

17 tariff approved by the state agency which regulates retail sales of
18 natural gas.
19 (c) Public utility districts may sell renewable natural gas,
20 green electrolytic hydrogen, or renewable hydrogen at wholesale or to
21 an end-use customer through a pipeline directly from renewable
22 natural gas, green electrolytic hydrogen, or renewable hydrogen
23 production facilities to facilities that compress, liquefy, or
24 dispense compressed natural gas, liquefied natural gas, green
25 electrolytic hydrogen, or renewable hydrogen fuel for end use as a
26 transportation fuel.
27 (d) Public utility districts may sell green electrolytic hydrogen
28 or renewable hydrogen at wholesale or to an end-use customer in
29 pressurized containers directly from green electrolytic hydrogen or
30 renewable hydrogen production facilities to facilities that utilize
31 green electrolytic hydrogen or renewable hydrogen as a nonutility
32 related input for a manufacturing process.
33 (e) Public utility districts may sell to an end-use customer or
34 at wholesale biogenic carbon dioxide, and other marketable coproducts

28 section unless the context clearly requires otherwise.

32 from a fossil fuel feedstock.
33 (b) "Renewable natural gas" means a gas consisting largely of
34 methane and other hydrocarbons derived from the decomposition of
35 organic material in landfills, wastewater treatment facilities, and
36 anaerobic digesters.
37 (c) "Renewable hydrogen" means hydrogen produced using renewable
