Title

Proposed Regulation 11, Rule 17: Low Use Compression Ignition (Diesel) Engines in Agricultural Use

Description

This proposed new rule is concerned primarily with low-use diesel driven water pumps used to protect agricultural crops from frost on cold winter nights. The ATCM required existing stationary agricultural diesel engines greater than 15 years old and greater than 100 HP (most engines) to meet emission standards by 12/31/2010, and those diesel engines from 50-100 HP to meet emission standards by 12/31/2011. The ATCM exempts agricultural wind machines and agricultural emergency generators. However, the ATCM does not provide any alternate compliance plan that will allow existing Tier 0 and Tier 1 engines that are used less than 100 hours per year averaged over three years and are either located no less than 1000 feet from a residential area, school or health facility or conduct a successful Health risk Screening Analysis to be used through December 31, 2020. The alternate compliance plan allows Tier 2 engines that meet these criteria to operate through December 31, 2025. Additional provisions provide for additional use during extreme frost seasons, exempt engines used less than 20 hours per year and establish the criteria for utilizing the alternate compliance plan.
