   1.                                                   We note you reference
the Business section for information regarding your RNG and
                                                        renewable power
projects and on page 10 you state that you own and operate 7 RNG
                                                        projects and 18
renewable power projects, and you provide a list of RNG projects in
                                                        operation and under
construction, along with the design capacity in MMbtus per year.

                                                        However, it appears you
have limited similar disclosure concerning the renewable power
                                                        projects to page 66 of
MD&A, where you provide a list of these projects along with their
                                                        nameplate capacity in
MW per hour. We suggest that you reposition information
                                                        regarding your physical
properties to a common section of the filing.

         We believe that additional information should be provided to comply
with Instruction 1 to
         Item 102 of Regulation S-K, to include information that will
reasonably inform investors
         as to the suitability, adequacy, productive capacity, and extent of
utilization.

         For example, disclose the timeframes for completion of the various RNG
projects under
         construction, and the status of the renewable power projects such as
the relevance and
         implications of being an RNG conversion candidate and the timeframes
for conversion
         completion for projects where you have indicated conversion is
possible.

         Please also disclose the extent of utilization of the various
facilities for each period,
         relative to the design or nameplate capacity information you have
disclosed and clarify
         whether utilization has been consistent with your expectations.

2.       We understand from the tables on pages 64 and 65 that you produced 2.2
million MMbtu's
         during 2022 from RNG projects having a design capacity of 3.9 million
MMBtu's,
         indicating these projects were performing at 56% of the design
capacity.

         Please expand your disclosures to clarify the extent to which you
expect this relationship
         between production and design capacity to continue or to change, and
describe any
         underlying factors that are reasonably likely to alter the
relationship.

         Please describe any uncertainties concerning variables that would
determine whether
         production at or near the design capacity is reasonably likely to
occur.

Revenues, page 67

3.       We note your disclosures of changes in revenues for RNG Fuel, Fuel
Station Services, and
         Renewable Power, in which you identify various additional products,
such as methanol
         pathway credits, brown gas sales, environmental credits, and
transportation fuel.

         Please expand your disclosures to indicate the extent to which
material changes in net
         sales are attributable to changes in prices or to changes in the
volume or the amount of
         goods or services being sold to comply with Item 303(b)(2) of
Regulation S-K.

         Given the number of products identified, it would be helpful to
include a tabulation with
         comparative sales and volumetric details for each product.

         Please include descriptions of the methanol pathway credits and brown
gas and
         provide any details necessary to understand the underlying drivers.

4.       We note your accounting policy disclosure explaining that sales of
environmental
         attributes are generally recognized when the related certificates are
delivered to a buyer
         although you may recognize the sales in conjunction with sales of RNG
or renewable
         power if the contract provides that title to the environmental
attributes will transfer when
         such products are produced, and the price to the buyer is fixed and
collection of the
         proceeds will occur within 60 days after generation of the renewable
power.

         However, in the earnings releases you have furnished on Form 8-K for
the year and
         subsequent interim quarters, you present the non-GAAP measure of
Adjusted EBITDA,
         which reflects an adjustment for "RNG Pending Certification and Unsold
Environmental
         Credits." You indicate the reason for this adjustment is to "better
align timing of revenues
         to when costs are recognized for the production of RNG...."

         Tell us why you believe that adding anticipated future sales of
environmental attributes to
         your non-GAAP performance measure should not be regarded as contrary
to the guidance
         in Question 100.04 of our Compliance and Disclosure Interpretations
pertaining to Non-
         GAAP Financial Measures, which you may view on our website at the
following address:
         https://www.sec.gov/corpfin/non-gaap-financial-measures.htm

         As your adjustment effectively changes the recognition and measurement
principles
         required under GAAP, please clarify how your individually-tailored
adjustment does not
         yield a potentially misleading non-GAAP measure, in your view.

        We remind you that the company and its management are responsible for
the accuracy
and adequacy of their disclosures, notwithstanding any review, comments, action
or absence of
action by the staff.

      You may contact Mark Wojciechowski, Staff Accountant, at (202) 551-3759
or John
Cannarella, Staff Accountant, at (202) 551-3337 if you have any questions.
