Wastewater Treatment Plant Design and Testing – Statement of Qualifications

PES staff conducts wastewater effluent testing to demonstrate compliance with existing State permit conditions or Federal effluent limits. Our staff’s experience includes operating biological and physical/chemical wastewater treatment plants.

• PES uses its testing laboratory to conduct effluent testing at various manufacturing facilities. Jar tests calculate dosing of various coagulants: lime, alum, ferric chloride, and cationic or anionic polymers. Optimum dosing reduces operating costs.



Wastewater Discharge Permitting

  • Industrial pretreatment program permitting for new facilities and modifications to existing dischargers.
  • Stormwater discharges via NPDES General Permits.
  • Mine dewatering NPDES permits.
  • Wastewater sludge disposal and RCRA manifests.



Wastewater Regulation Experience 

  • Conducted a wastewater research program for EPA to evaluate hazardous waste streams for delisting  as categorically regulated.  This effort for the Office of Solid Waste addressed mineral processing, iron and steel production, coke production, and electroplating industries.
  • Relating manufacturing process conditions to effluent analytical testing results.




Wastewater Treatment Plant Operational Experience

  • Operating biological and physical wastewater treatment plants.

Spill Prevention Control & Countermeasures Plan – Statement of Qualifications

PES staff prepares Spill Prevention Control & Countermeasures Plans (SPCCs). These evaluations can quantify the potential contribution(s) of releases from petroleum storage tanks to streams or lakes. More importantly, these plans lay out site-specific work practice controls to prevent releases. Our staff’s experience includes quarries, industrial sites, and petroleum distribution sites.

SPCC Plans apply to facilities that have petroleum product tanks greater than 1,320 gallons. The plan must address:
  • Facility drainage,
  • Diked areas (secondary containment),
  • Tank materials,
  • Inspections and testing,
  • Transfer operations,
  • Recordkeeping, and
  • Training.


SPCC Experience includes:

  • Developing and upgrading SPCC Plans.
  • Developing site maps from geographical information systems. This is an economical alternative to surveying that provides adequate representation of equipment placement and area calculations.
  • Calculating the volume of stormwater in diked areas and in overland flow for NPDES discharges.
  • Conducting evaluations of noncompliance on stream water quality.
  • Conducting facility compliance inspections for SPCC Plan compliance.

Also of note:

  • SPCC regulations also cover mobile tanks used at the facility.
  • 55-gallon drums are the smallest unit of measure addressed by SPCC regulations.
