There will never be a "one size fits all" in emergency planning. For one thing, there are too many types of planning environments, with each type having its own issues and needs. This does not mean that good model plans would not be helpful. The more information is shared and notes compared between LEPCs, the more effective they are.
There are eight planning environments:
Their needs will be quite different, unique, and diverse.
And government itself has multiple roles in emergency planning. Government is employer, disaster planner, regulator, and responder. The private sector has an obligation to plan, and is a response partner.
All emergency plans need to be tested and validated. LEPCs are expected by law to evaluate the need for resources and methods to exercise their emergency plans.
Somehow the gist and thrust of emergency planning also needs to be communicated to a professional group with little or no involvement in the emergency planning process: Zoning and Planning Agencies, Economic Development Agencies, and Community Planning Agencies. These agencies can prevent dangerous situations and disasters by NOT placing incompatible land uses near one another. It makes sense to keep hospitals, nursing homes, schools, and day care centers AWAY from the area where a spill of chemicals may reach. When there is plenty of land available for industrial and facility siting, it makes sense to examine these issues. Unfortunately, these agencies do not often have an understanding or even an inkling of the existence of EPCRA.
