Wastewater Pre-Treatment Audit Checklist for Breweries & Beverage Plants [FREE PDF]

Breweries, wineries, and beverage manufacturing facilities generate high-strength wastewater with elevated biochemical oxygen demand (BOD), pH extremes, and suspended solids that must meet local Publicly Owned Treatment Works (POTW) discharge limits under EPA 40 CFR Part 403 General Pretreatment Regulations. Failure to comply with industrial pretreatment permits can result in significant fines, permit revocation, and operational shutdowns. FSMA Preventive Controls under 21 CFR Part 117 also requ

  • Industry: Brewery
  • Frequency: Monthly
  • Estimated Time: 50-70 minutes
  • Role: Production Manager
  • Total Items: 37
  • Compliance: EPA 40 CFR Part 403 - General Pretreatment Regulations, EPA 40 CFR Part 122 - NPDES Permit Program, FDA 21 CFR 110.35 - Sanitary Operations, FSMA 21 CFR Part 117 - Preventive Controls for Human Food, OSHA 29 CFR 1910.146 - Permit-Required Confined Spaces

Permit & Regulatory Compliance Documentation

Confirm that all required permits, self-monitoring reports, and regulatory correspondence are current.

  • Is the current industrial pretreatment permit on file and within its valid date range?
  • Have all required self-monitoring reports been submitted to the POTW on schedule?
  • Are copies of all POTW correspondence and violation notices retained for at least 3 years?
  • Have any permit exceedances been reported to the POTW within the required timeframe?
  • Is the facility classified correctly as a Significant Industrial User (SIU) or Non-Significant IU?

Effluent Discharge Limits & Monitoring

Verify that current effluent parameters comply with permit discharge limits for key pollutants.

  • Is influent wastewater pH measured and recorded at the required frequency?
  • What is the current effluent pH reading?
  • Are BOD (Biochemical Oxygen Demand) levels being monitored and within permitted limits?
  • Are total suspended solids (TSS) measurements within permit limits?
  • Are flow measurement devices calibrated and recording total daily discharge volume accurately?

Pre-Treatment Equipment Condition

Inspect physical condition and operational status of all pretreatment infrastructure.

  • Is the equalization tank (EQ tank) operating within its design volume and free from structural damage?
  • Are pH adjustment systems (acid/caustic dosing) functional and correctly calibrated?
  • Is the dissolved air flotation (DAF) or settling system free from mechanical issues and producing acceptable effluent?
  • Are all pumps, blowers, and aeration equipment in the pretreatment system operational?
  • Is the pretreatment area free from wastewater spills, overflows, or uncontained discharges?
  • Please attach a photo of the current equalization tank level indicator and pH display?

Sampling Procedures & Laboratory Analysis

Verify that sampling methods, chain of custody, and lab analysis protocols meet regulatory requirements.

  • Are wastewater samples collected using EPA-approved methods (composite vs. grab as required by permit)?
  • Are sample collection points accessible, clearly labeled, and located at the correct monitoring point?
  • Is the laboratory conducting analysis certified for required parameters under the state's NELAP program?
  • Are chain of custody (COC) forms completed correctly and retained with each sample set?
  • Are calibration logs for in-house meters (pH, dissolved oxygen, temperature) maintained and current?

Solids & By-Product Management

Assess handling, storage, and disposal of spent grains, yeast, hop solids, and treatment sludge.

  • Are spent grains, yeast, and hop material diverted from the wastewater system prior to discharge?
  • Is pretreatment sludge from the DAF or settling system characterized and disposed of properly?
  • Are storage containers for sludge and by-products properly labeled and protected from stormwater contact?
  • Is the volume and disposal destination of all sludge and solid waste documented in manifests or records?
  • Are by-products intended for animal feed (spent grains) stored hygienically and free from contamination?

Spill Prevention & Emergency Response

Evaluate spill containment infrastructure, emergency plans, and notification procedures.

  • Is a Spill Prevention, Control, and Countermeasure (SPCC) plan in place if oil storage exceeds threshold volumes?
  • Are all floor drains in production areas connected to the pretreatment system (not to storm drains)?
  • Is secondary containment installed and adequate for chemical storage tanks (acids, caustics, treatment chemicals)?
  • Is there a documented emergency notification procedure for spills that reach or threaten the POTW?
  • Are spill response kits (absorbents, drain plugs, PPE) readily accessible in production and pretreatment areas?

Confined Space Safety for Pretreatment Structures

Verify confined space program compliance for tanks, manholes, and pits associated with pretreatment systems.

  • Are all permit-required confined spaces (equalization tanks, manholes, pits) identified and marked with warning signs?
  • Is a written permit-required confined space entry program available and implemented?
  • Are atmospheric testing instruments (oxygen, LEL, H2S, CO) available, calibrated, and used before every entry?
  • Are confined space entry permits being completed and retained for each entry event?
  • Have all workers who may enter confined spaces completed OSHA-compliant confined space training?
  • Please note any additional findings, corrective actions required, or follow-up items from this audit.
