Introduction

2019 Water Resource Recovery Facilities Co-Digestion System Survey
Thank you for your continued participation in EPA’s AD data collection project!
The survey has been streamlined making it even easier to submit your data. Two years of operating data (2017 and 2018) will be
collected this yea. Completion of this survey is voluntary.
We hope the reports EPA has produced based on this data are useful to you and the rest of the biogas industry. As with previous years,
the data collected through this survey will also be aggregated prior to its release. Thank you for taking the time to provide survey data.
Your input is greatly appreciated.
The goals of this project have not changed. EPA is collecting the data requested in this survey to quantify and track the amount of food
waste processed and available processing capacity in the United States. The survey also requests information on types of feedstocks
processed, the sources of feedstocks and the end uses of anaerobic digestion products. This year (2019) is the third year of the
project.
Please contact us with any questions about the survey or suggestions for improvement.
The public reporting and record keeping burden for this collection of information is estimated to average 30 minutes per response. Send comments on the
Agency's need for this information, the accuracy of the provided burden estimates, and any suggested methods for minimizing respondent burden, including
through the use of automated collection techniques to the Director, Collection Strategies Division, U.S. Environmental Protection Agency (2822T), 1200
Pennsylvania Ave., NW, Washington, D.C. 20460. Include the OMB control number in any correspondence. Do not send the completed form to this address.

WRRF Digestion Capacity

Instructions: It is assumed that the primary feedstock treated in the digester(s) at your facility is solids from your wastewater collection
system. The following questions are designed to provide information about the capacity of your facility for co-digesting feedstocks
other than wastewater solids. EPA is trying to determine how much outside feedstock could potentially be processed at your WRRF. If
you had an unlimited amount of feedstock available to you – how much could you process in a year?
Later questions in this survey will ask how much food waste and non-food waste were processed or co-digested in your digesters in
2017 and 2018. The combined amount of food waste and non-food waste processed in any given year should be less than or equal to
the available capacity reported below.

* 14. Please identify your facility’s available capacity to accept feedstocks from offsite sources.

* 15. Please indicate if this available capacity for processing feedstocks (other than wastewater solids from
your collection system) is provided in gallons per year or tons per year.

16. Please briefly describe how you calculated the available capacity to accept feedstocks from offsite
sources.
