Indiana State Department of Health Commercial On-Site Sewage System Submittal

and Review Process

• On-site soil evaluation◦ Indiana Registry of Soil

Scientists◦ Forwards report to ISDH◦ soil@isdh.in.gov

• Pre-application

The Process…

Local Health Department – 10 Day Comment Period

If there is an existing system that is in failure, or the facility is under a pump and haul order;

Availability of sanitary sewer; Proximity to any wells; Has the site been disturbed, or has construction begun; Restricted site conditions (i.e. floodplain, filled depressional areas,

sinkholes, etc.); Availability of perimeter drain outlet and approximate depth, if

needed; Any reservations you may have about the installation of an on-site

system in this location; and, Any additional information you feel is pertinent to the site.

The Process…

Pre-application – see “Handout #2”

The Process…

The Process…Technical Data Sheet (TDS) – See “Handout #3”

◦ Minimum specifications for design◦ ISDH vs Local Health Department Review◦ Design daily flow◦ Grease trap required?◦ Secondary treatment required?◦ Subsurface soil absorption field eligible?

• Gravity and/or flood dose?• 25% sizing reduction (chambers) eligible?• Drainage required?• Sand line system eligible?

The Process…

Technical Data Sheet (TDS) – See “Handout #3”

◦ Email sent to owner/designated agent and county health department representative with the following attachments: TDS Commercial rule 410 IAC 6-10.1 Plan submittal requirements – see “Handout #4” OSS components checklist – see “Handout #5” Incomplete application for construction permit

checklist New designer checklist

The Process…• Delegation to Local Health Department (LHD)◦ Design daily flow (DDF) ≤ 750 gpd◦ LHD staff approved for delegation◦ Indicated on cover letter and TDS (in writing)

Options1. All plans must be submitted

to ISDH2. Gravity to be reviewed by

LHD, systems with pump by ISDH

3. Subsurface to be reviewed by LHD, elevated to ISDH

4. All can be reviewed by LHD

The Process… CHANGED!!!!

o New law – effective January 1, 2017o Requires written acknowledgment of receipt within

one business day and name of assigned staff persono Requires review of initial submittals within 30 business
