Larchwood, Iowa
Establish with Stockwell how the planned maintenance affects treatment requirements and whether the facilities study can consider a pretreatment option that reduces the load reaching the lagoon.
PolicySight’s approach
PolicySight’s recommended sequence, not an official approval chain.
1. Facilities study authorized by council
September 14 minutes record approval of Stockwell’s lagoon facilities plan.
2. Remaining treatment need
Confirm the alternatives under comparison and the ammonia need after planned maintenance.
3. Existing evidence mapped to Iowa
Set Kingsville and Vancouver results against section 4.4.3 for engineer and DNR discussion.
4. Comparison by the engineer, if accepted
A bounded comparison within the study, scoped with Stockwell.
