Dear Mr. Ashack,
Thank you for asking Webster Environmental Associates, Inc. (WEA) to submit this Agreement for the
above referenced project. This Agreement is based on the meeting held on January 24, 2024 following the
review of proposals for the Jeffersonville Collection System Calcium Nitrate Solution Supply and
Odor Control Service.
Jeffersonville currently has a contract with Aulick to supply calcium nitrate for their wastewater sewer
collection system. That Vendor provides the chemical and conducts some basic monitoring. With
implementation of the new contract to be in effect in February or March, additional efforts are expected
from the Vendor. WEA has been asked to provide assistance managing this project and make
recommendations for the best interest of Jeffersonville as it relates to odor control chemical supply and
equipment service. WEA will serve as Jeffersonville's advocate on the contract to ensure efficient use of
available resources and effective odor control. WEA shall provide the following scope of work (to be
provided at Jeffersonville's request):
• Assist with the setup of the contract with the successful Vendor. Provide the Request for Proposals
document with all Addenda items inserted to be used as a concise basis for contractual requirements.
• Review information regarding factors impacting H2S and odor production in Jeffersonville's
collection system. Refine the Condition Assessment information to provide a technically defensible
basis for prioritization of resources. Assist Jeffersonville with working through the Decision Matrices
for prioritizing each of the chemical feed sites and establishing performance goals for each site.
• Work with the Vendor to refine the formatting of the reports to make sure they include all of the
information that is truly helpful to Jeffersonville in making dosage adjustment decisions. For instance,
- Develop chemical usage budgets for each location and monitor the progress in each report.
- Identify how much chemical was used at each of the stations in previous month,not just how much
was used in total.
- Provide status of chemical budget relative to projections for the month and the year.
- Additionally, WEA will incorporate information from others to ensure optimal reporting and
service.
• Review and comment on information provided in each of the Vendor's monthly reports.

• Provide some evaluation as to why H2S levels are higher than anticipated. Provide comments
regarding other treatment alternatives if applicable. (Studies or full technical evaluations can be
provided under a separate scope.)
• Conduct sulfide sampling and provide theoretical chemical dosages for each of the feed sites. This
information can be used for comparison to and a basis for recommending adjustments to the current
dosage rates.
• Check maintenance records to verify sufficient information provided.
• Recommend adjustments to existing timers or installation of new timers(to optimize chemical feed
during highest H2S/odor periods).
• Train Jeffersonville's Odor Control Specialist to be ready to manage the entire system allowing
