1 Municipal/Industrial Partnership in WWTP Expansion MWEA Biosolids & IPP Joint Conference September 27 & 28, 2011 Kalamazoo, MI

2 Purpose Historical Perspective of the Relationship Between the City of Kalamazoo and Pfizer, Inc. (formerly, Pharmacia & The Upjohn Co.) In the Beginning.... Early Operational Challenges... The Turning Point.... Continued Collaboration... Mid Course Correction...

3 In the Beginning... there was wastewater lots of it! Site Prior to 1954

4 Upjohn/City of Kalamazoo Ties

5 In the Beginning... A Primary Treatment Plant was built in 1954 and placed into operation on February 22, Operated through the 1960 s Average Daily Flow of 12 mgd

6 Initial Relationship Wastewater Contract with The Upjohn Company July 27, 1964 Started discharge to City of Kalamazoo Primary WWTP Company previously operated their own treatment plant Treatment

7 Early Operational Challenges Mid to Late 1960 s Chlorine interference Anaerobic Digester Operational Problems Solids pumped to lagoons east side of City Odor problems persisted Traced to chemical constituents from Upjohn s discharge

8 Initial Response s Low Pressure Oxidation Sludge Conditioning Dewatering Incineration

9 Operational Challenges Continued Upgrades in the 1970 s Expansion to Activated Sludge Mechanical Aerators Secondary Sedimentation Increased Loadings & Flow Solids overloading Poor Effluent

10 Operational Challenges... Expansion of the 1970 s plus adding papermills to wwtp exceeded flow and loading capacity Conducted Pilot Testing to treat difficult mix of industrial and domestic wastewater PACT selected due ability to protect micro organisms (nitrifying bacteria)

11 Turning Point.. Mid 1980 s Mid 1980 s - Numerous Plant Upgrades Federal/State grant funding New primary settling, Expanded secondary aeration, PACT w/wet Air Regeneration, and Tertiary sand filters.

12 Kalamazoo Water Reclamation Plant Following 1980 s Expansion

13 Categorical Pretreatment Challenge National Pretreatment Standards Pharmaceutical Manufacturing Standard to address a legitimate problem in many communities nationwide. Undo considerable joint efforts Company would be required to spend tens of millions to build pretreatment facilities

14 Collaborative Approach Appeal to Congress, state government, local boards, local environmental organizations Company and City went to Washington DC seeking political support Produced a legislative exemption for any pharmaceutical manufacturer in Kalamazoo

15 State Regulatory Approval Federal Exemption Extensive pilot plant studies conducted 17 finger print compounds of concern Treatability assessed for each Pilot Plant effluent was well within federal pretreatment standards (as well as final effluent discharge standards)

16 Outcomes Integrity of POTW design maintained; avoided costly redesign Company avoided spending tens of millions for pretreatment facilities Redirected to a more productive use Avoided potential loss of significant employer

17 Continuing Collaborations Used Pilot Plant at various flows and loadings to determine treatability of waste stream that had been formally discharged to deep well injection system New products, chemical constituents tested in respirometer or pilot plant KWRP notified when production changes and releases have occurred

18 Continuing Collaborations Mutually beneficial exchange of ideas and issues Fostered an atmosphere that allows for quick and efficient response to concerns expressed by both parties Pilot tests have allowed Pfizer to utilize the unique capabilities of KWRP City to more fully utilize existing treatment capacity.

19 Mid Course Correction... Current plant upgrades include Converting the conventional activated sludge system to a Biological Nutrient Removal system Converting from coarse bubble to fine bubble diffusers

20 Mid Course Correction... Current plant upgrades include Replacing existing blowers with smaller more energy efficient blowers. These upgrades will allow the KWRP to meet the Total Maximum Daily Loading (TMDL) requirements for phosphorus and lower secondary aeration energy usage.
