Management of Contaminated Wipes and Reusable Cloth

On July 3, 2015 the Indiana Department of Environmental Management’s (IDEM) Hazardous Waste Updates, LSA Document #14-288(F) [PDF], rulemaking became effective. This rulemaking incorporates by reference federal revisions to conditionally exclude solvent-contaminated wipes from solid waste requirements if the wipes are cleaned and reused in accordance with 40 CFR 261.4(a)(26) and hazardous waste requirements if the wipes are disposed in accordance with 40 CFR 261.4(b)(18).

As a result of this incorporation by reference of federal revision, Waste-0010-NPD, Management of Contaminated Wipes, has been repealed. In-lieu of Waste-0010-NPD, IDEM has developed the Management of Contaminated Wipes and Reusable Cloth Items [PDF] guidance document.

This document provides hazardous waste generators, handlers, and other interested parties an overview of the federal Solvent Contaminated Wipes Rule, as well as IDEM’s current policy for the management of wipes, gloves, clothing, and cloth items that are contaminated with other hazardous waste. IDEM’s Office of Land Quality (OLQ) Hazardous Waste Resources webpage provides further guidance.

2015 NetDMR Incentive Available!

The Indiana Department of Environmental Management (IDEM) is offering a new incentive for Indiana certified wastewater operators [PDF] who prepare Discharge Monitoring Reports (DMR), Monthly Monitoring Reports (MMR) or Monthly Reports of Operation (MRO) and have not yet utilized NetDMR. If the NetDMR enrollment process has been completed and a DMR as well as any applicable MMR or MRO has been successfully submitted utilizing NetDMR live/production prior to the effective date of the federal National Pollutant Discharge Elimination System (NPDES) Electronic Reporting rule (anticipated to be by the end of 2015) or by December 31, 2015, whichever comes first, IDEM will grant two technical contact hours toward the renewal of a wastewater operator’s license.

Please note, to gain the two technical contact hours the congratulatory e-mail (e-mail received from IDEM upon successful submittal of DMR along with its corresponding MMR/MRO) must be submitted with the Wastewater Operator/Apprentice Continuing Education Credit Report - State Form 51139 (available on the IDEM Forms page) to IDEM. This incentive is only available once per person per permit.
