Septage Management

Septic wastewater comes from domestic septic tanks, holding tanks, privies, seepage pits, cesspools, compost toilets, portable sanitary units, and restaurant traps and interceptors for animal and vegetable grease. To prevent threats to human health or the environment, septage must be managed according to laws in the Indiana Code (IC 13-18-12) and rules in the Indiana Administrative Code (327 IAC 7.1 [PDF]).

IDEM oversees the requirements for the removal, transport, storage, treatment, and disposal of septage from sewage disposal systems. Persons who remove septage from sewage disposal systems and transport, store, treat, and/or dispose of septage (including land application) must obtain a septage management permit from IDEM before they begin operations. They also must comply with other applicable requirements in 327 IAC 7.1.

Septage may be transported to, and discharged into, permitted wastewater treatment plants or storage/treatment facilities designed to store/treat domestic septage and restaurant grease from traps or interceptors. Treated septage may be land applied on agricultural fields as a soil amendment and fertilizer at controlled rates.

Requirements for Homeowners, Recreational Boaters, and Marinas

Homeowners who clean and service their own residential sewage disposal systems are exempt from requirements to obtain a permit, but transport and disposal of septage, including land application, must be done in accordance with the law. Guidance on Land Application of Septage for Homeowners [PDF] is available from IDEM.

Recreational boaters with on-board toilets and wastewater holding tanks (i.e., marine sanitation devices) and marina owners/operators with marine pumpouts, dump stations, and/or floating restrooms must properly dispose of septage. The contents of Type III marine sanitation devices may not be land applied. Guidance for boaters and information on Clean Vessel Act grants and sewage management practices for marina owners/operators is available on IDEM’s Partnerships and Recognition Programs portal.

Exclusions

Activities that are excluded from regulation under 327 IAC 7.1 are identified in 327 IAC 7.1-1-3 [PDF].

Applicable permits are issued in one permit document, which is valid for 3 years unless IDEM establishes an alternate length (327 IAC 7.1-8-3). Applicants are not required to give public notice. IDEM issues septage permits within 90 days of receiving a complete application. If land application is involved, the agency has 180 days for processing. Septage permits are nontransferable.

Reporting Requirements

Persons with land application site permits must complete and submit to IDEM a Septage Land Application Quarterly Report (State Form 50397, available on the IDEM Forms page) for each approved site by the end of the month following each quarter. For example, the second quarter report is due by the end of July. Permittees can submit their report(s):

If certain land application sites are not used during a quarter, permittees must identify those sites (include the site identification number) in a cover letter, fax, or email to IDEM in lieu of submitting a report for each unused site.
