Updating the Dearborn County “Clean Water”

Plan: An Overview

Jane Wittke, OKI

Update Support

OKI has been able to undertake this update because of funding provided by the Indiana Department of Environmental Management ($90,437).

OKI has also been able to undertake this update because of the knowledge and support of the local project partners.

What We’ll Cover:Why We’re Doing an Update of the PlanSteps in the Plan Update ProcessClarifying What This Planning Does &

D0esn’t DoSummary of Findings, Including:

Current Water Quality InformationTypes of Water Pollution SourcesPopulation and Land Use TrendsIdentifying Wastewater FPAs & DMAs

Water Quality Management Plans are required

under Section 208 of the federal Clean Water Act,

thus are sometimes called “208 “ Plans for short.

Steps in the Plan Update Process:Drafts Shared with the Advisory Committee

& PublicRevised Draft Now Available for Public

Feedback until June 8Public Feedback & Final Draft Update to

Advisory Committee on June 13Plan Finalized by JulyPlan Presented to OKI Executive Committee

for action in August or SeptemberAfter OKI action, adopted plan update

submitted to IDEM

What This Planning DoesDescribes current water quality problemsIdentifies management needs and approaches

to solving water quality problemsIdentifies areas where population trends and

anticipated land use changes indicate probable needs for increased wastewater treatment

Clarifies which wastewater management agencies are designated to provide treatment in which areas

Enables the state of Indiana to comply with federal law in issuing wastewater discharge permits

What this Planning Doesn’t DoDoesn’t involve doing add’l water quality

monitoringDoesn’t enable detailed identification of

water pollution causesDoesn’t involve changes in state laws

requiring sewer hook-ups at certain distances from a centralized system

Doesn’t provide funding for pollution controls (e.g. to correct sewer overflows, failing septic systems)

Dearborn County Impairments Include:• lowered dissolved oxygen• E. coli• impaired biotic communities• mercury in fish tissue• PCBs in fish tissue

Dearborn Water Impairments:Potential SourcesLowered Dissolved Oxygen

Channelization and thermal discharges from industry

E. coliHuman and Animal WasteIndicates conditions which breed viral,

bacterial, and protozoan pathogensImpaired Biotic Communities

Can be a result of other impairments listedInhibits natural processes that affect water

quality

Dearborn Water Impairments:Potential SourcesMercury in Fish Tissue (Methylmercury)

Air emissions from power generation, and other industrial waste disposal activities

PCBs in Fish TissuePCBs banned in US in 1979Uses include electrical transformers, heat

transfer systems, and many morePCBs are fat soluble and can be stored over

long periods of time in sediment and living tissue

Examining Types of

Water Pollution SourcesNonpoint sources are diffuse runoff from

land into water;

Point sources come from a specific point like a sewer or industrial discharge pipe.

Dearborn County’s NPS Issues:

septic tank dischargessedimentation & siltationnutrient run offfloatables and other trashunrestricted cattle access
