This is a “Golden Opportunity” for Awareness Educators, Scientists, and Concerned Citizens to present their concerns, evidence, test results, and data to OEHHA – The Office of Environmental Health Hazard Assessment who have full control as well as the ability to end Solar Radiation Management #SRM, a form of Geoengineering often referred to as Chemtrails, Chemclouds, chemsprays, and chembombs, often confused with “persistent contrails” which require prime conditions that rarely exist during summer months.
The Office of Environmental Health Hazard Assessment (OEHHA) released a draft document, Air Toxics Hot Spots Program Guidance Manual for the Preparation of Risk Assessments (Guidance Manual) on June 20, 2014 for a 45-day public comment period, originally scheduled to end on August 4, 2014. We received a request from the California Chamber of Commerce on behalf of various business groups to extend the public comment period. This notice extends the comment period to August 18, 2014.
This draft Guidance Manual has been developed by OEHHA, in conjunction with the Air Resources Board, for use in implementing the Air Toxics Hot Spots Program (Health and Safety Code Section 44360 et. seq.). OEHHA is required to develop guidelines for conducting health risk assessments under Section 44360(b)(2).
As stated in the original June 20, 2014 notice, we are seeking comment primarily on clarity of the guidance manual as it relates to implementing and integrating the risk assessment guidelines presented in three OEHHA Technical Support Documents (TSDs). These TSDs, completed in 2008, 2009 and 2012, describe non-cancer risk assessment, derivation of cancer potency factors, and exposure assessment methodology including stochastic risk assessment. We are not seeking comments on the underlying scientific information that originally appeared in the TSDs, which have undergone public and peer review, approval by the Scientific Review Panel, and adoption by OEHHA. However, we are seeking comments on specific items noted below that TSDs were silent on or that represent slight corrections. As noted in the June 20 request for comment notice, these specific items are: Read the full article by clicking here
If you are interested in making a comment please note:
OEHHA will review all relevant comments and revise the draft manual as appropriate. The Scientific Review Panel will then review the document for clarity and its overall implementation and integration of the TSDs, including text related to the specific items cited above. Please note that we cannot consider comments on regulatory impacts that may eventually result from efforts to reduce risks identified in future assessments conducted pursuant to the guidance manual. These considerations are outside the jurisdiction of the guidance manual and OEHHA. The California Air Resources Board and the state’s local air districts will consider regulatory impacts as part of their ongoing implementation of the Air Toxics Hot Spots Program.
The Guidance Manual is available on the OEHHA’s web site.
