Associate - Emergency Response Contractors
Any firm or corporation not eligible for Producer or Packager/Bleach Producer membership, but who are interested in the continued development and improvement of the chlor-alkali industry; involved in supplying the chlor-alkali industry; users of its products; or producers and users of hydrogen chloride.
Emergency Response Contractors are a special sub-category of Associate Membership that, if eligible, the company receives a reduced membership fee. To qualify for this category, your company must be successfully verified by CI in accordance with the Chlorine Emergency Plan (CHLOREP) Contractor Verification Program requirements. If an emergency response contractor does not successfully pass verification and wishes to continue as a CI member, the company may do so as a regular Associate Member and pay the fee associated with that category. (Companies applying for this category should request a copy of the CHLOREP Contractor Verification Program description, which includes information about the process and requirements.)
