Sewage Sludge Reporting: NeT-Biosolids (NETBIO)

Find out how to submit sludge data to TCEQ for your Texas Pollutant Discharge Elimination System (TPDES) permit.

Submitting Your Report Electronically

Submit TPDES annual program reports for Sewage Sludge or Biosolids through EPA’s National Pollutant Discharge Elimination System eReporting Tool for Biosolids (“NETBIO”). This includes sludge data previously submitted on paper discharge monitoring reports (DMRs), supplemental paper reports, or through NetDMR.

Access the NETBIO Tool at EPA’s Central Data Exchange (CDX)

Request an Electronic Reporting Waiver - If you cannot submit your annual report electronically as required, submit a Request for Electronic Reporting Waiver form (TCEQ-20754).

Roles and Signatory Authority

Understand Your Role

  • Signatory: Can sign, submit, manage, prepare, and edit all forms.
  • Preparer: Can prepare all forms on behalf of the signatory at the facility but cannot sign or submit the report. Find out how to submit your report to a signatory on page 46 of the Biosolids User’s Guide .

Request Access to Your Facility - Once you have access to the NETBIO program, someone with the signatory role must request access to your facility's records. Then they can grant others access to the facility information.

If you have trouble logging in or setting up an account, contact the CDX Helpdesk:

Delegate Signatory Authority to a person or position responsible for environmental matters or the overall operation of your facility.

Monitoring Periods and Deadline

Submit your report by the deadline, Sept. 30, for the Sept. 1, 2022 to Aug. 31, 2023 monitoring (reporting) period (Title 30, Texas Administrative Code, (30 TAC) Section 312.48 ).

Do not submit a paper report to TCEQ’s central or regional offices. When you submit your annual report electronically, our staff can access the information.

How to Complete the Report

Find the TCEQ Registration Number - The number referenced in the report for sludge transporters is a five-digit registration number that starts with 2.

Convert Metric Tons to Dry Metric Tons - See page 94 of the Biosolids User's Guide for formulas to complete this conversion.

Identify Class I Sludge Management Facilities - A Class I sludge management facility (40 CFR 501.2 ) is any:

  • Publicly Owned Treatment Works (POTW) that must have an approved pretreatment program.
  • Treatment works classified as such because its sludge use or disposal practices could adversely affect public health or the environment.

For detailed instructions on How to Complete the Biosolids or Sewage Sludge Management Section of the form, visit the EPA's website.

When You did not Produce Sludge or Biosolids

Even if your facility did not produce any sludge or biosolids during the current monitoring period, you must submit a report. Complete the following fields according to the answers below.

Program Information

  • If your facility is a POTW - Enter 0 for the estimated total amount of sewage sludge produced at your facility for the reporting period (in dry metric tons)
  • If not a POTW - Enter 0 for the estimated total amount of biosolids produced at your facility for the reporting period (in dry metric tons).

Treatment Processes

  • Physical Treatment Operations - Leave all available options blank.
  • Other Processes to Manage Sewage Sludge - Select the “Other Treatment Process” option and enter “no sludge production this monitoring period” in the text box provided.

Analytical Methods

  • Did you or your facility collect sewage sludge or biosolids samples for laboratory analysis? Select “No Analytical Methods Used.”

Biosolids/Sewage Sludge Management - Sewage Sludge Unique Identifier (SSUID) Section

  • Management Practice Type - Select “Other Management Practice.
  • Management Practice Detail - Select "Other."
  • Handler, Preparer, or Applier Type - Select "On-site Owner or Operator."
  • Pathogen Class - Select "Not Applicable."
  • Do you have any deficiencies to report for this SSUID? - Select an appropriate option.
  • Amount (dry metric tons) - Enter 0.
  • Other Management Practice Detail Description - Enter “no sludge production this monitoring period.

Click the “Done” button and then click “Submit.

When You Sent Sludge to Municipal Landfills

Pathogen Class - You may select "Not Applicable" from the Pathogen Class drop-down menu when sludge is sent to a municipal landfill.

Additional Fields - If you sent sludge to a municipal landfill, the form may ask for more compliance monitoring events than are required in your permit. Follow these steps to complete this section of the form:

  1. If the “Compliance Monitoring Periods” section is not already open, click the red error marker that appears under the “Monitoring Data Info” column.
  2. If you do not have data for a compliance monitoring event, select “No” under “Do you have analytical results to report for this monitoring period?
  3. Select an applicable option from the “Please indicate the reason for reporting no data for this compliance monitoring period” drop-down box.

Completing the Truck Hauling Template

Certification Statement - The certification statement you enter depends on your method of disposal and the requirements outlined in your permit. For example:

  • If you land apply bulk sewage sludge meeting any of the conditions below, use the applicable certification statement in 30 TAC 312.47(a)(4)(A)(ii) or 30 TAC 312.47(a)(5)(A)(ii)
    • Class A or Class AB or B pathogen reduction and the cumulative loading rates in Table 2 (Permit Section II)
    • Class B pathogen reduction and the pollutant concentrations in Table 3 (Permit Section II)
  • If you dispose of all sludge in a municipal solid waste landfill (Permit Section III), you must certify that the quality of the sewage sludge meets the requirements of 30 TAC 330 .
  • If you send your sludge to another facility for further processing (Permit Section IV), leave the “Certification Statement” column blank.

Document every load that was hauled in the spreadsheet template provided in NETBIO.
