Operating a Wood-Fired Boiler?

An area or major source of Hazardous Air Pollutants (HAP) utilizing a wood-fired boiler may be subject to the Boiler Maximum Achievable Control Technology (MACT) rules which may require stack testing, energy assessments, and boiler tune-up requirements.

A permitted source should evaluate the Potential to Emit (PTE) that was utilized to establish their air permit as it may need to be altered depending on the type of wood products combusted. The emission factor established for clean wood was most likely used to determine the PTE for an air permit issued to a facility utilizing a wood-fired boiler. Therefore, if a permitted source has been approved to combust clean wood but would like to combust or is combusting wood waste, the PTE should be re-evaluated to assist in gaining approval from the Indiana Department of Environmental Management (IDEM) and to update the air permit with correct information.

Metal Fabrication and Finishing Webpage Now Available!

The Indiana Department of Environmental Management (IDEM) now offers an informative Metal Fabrication and Finishing webpage assisting businesses utilizing dry abrasive blasting, dry machining, dry grinding, spray painting, and welding operations to determine whether requirements specified in 40 CFR 63, Subpart XXXXXX (6X) are being met. 6X regulates potential emissions of cadmium, chromium, lead, manganese, and nickel from dry abrasive blasting, dry machining, dry grinding, spray painting, and welding operations.

IDEM Offers Indiana Certified Wastewater Operators the Opportunity to Earn Four Technical Contact Hours

IDEM is offering an incentive of four technical contact hours toward the renewal of Indiana certified Wastewater Operator licenses for those who have not yet submitted their DMRs utilizing the NetDMR application and who enroll and successfully submit a DMR including the MMR/MRO utilizing NetDMR prior to December 31, 2014. This incentive is available once per operator and once per permit.

The U.S. EPA has proposed a new federal rule, the NPDES Electronic Reporting Rule, which will require all NPDES permit holders to submit/report NPDES compliance information electronically. This is an opportunity to start utilizing NetDMR and gain the incentive before it is federally mandated.

IDEM’s NetDMR webpage specifies more detailed information regarding the NetDMR tool and how to start utilizing it.

What Type of Solvent(s) Does Your Business Use?

Are you familiar with the solvent(s) being utilized within your cold cleaner degreaser operation?

Starting January 1, 2015, all persons who sell or purchase solvents for use in a cold cleaner degreaser operation will be required to keep the records specified within 326 IAC 8-3-8(c) including the true vapor pressure of the solvent. (The true vapor pressure is defined as “the equilibrium pressure exerted by a petroleum liquid as determined in accordance with methods described in American Petroleum Institute Bulletin 2517, “Evaporation Loss from Floating Roof Tanks,” 1962.”) A purchasing invoice or a copy of the manufacturer’s recommendation for the solvents utilized may include most of the required records.

In addition to speaking with Compliance and Technical Assistance Program (CTAP) staff, you may also visit the newly created Degreasing Operations webpage, for information on how to comply with state and federal regulations concerning degreasing, as well as tips to consider when evaluating solvent alternatives.
