Hazardous Materials Ordinance Changes
Environmental Health Services is proposing changes to County Ordinance 4.92 Storage of Hazardous Substances


Ordinance 4.92 has not been significantly updated in almost 20 years.  The purpose of the changes is to remove outdated requirements, align with existing State regulations, and provide clarification where needed.  The proposed changes will affect all businesses currently regulated for hazardous materials/waste storage and generation, but is not expected to increase their regulatory burden.  On the contrary, by removing outdated requirements, it will allow Environmental Health Services more flexibility to revise permit conditions and policies based on current best practices and specific site conditions.
