(c) The HMIS may report the amount of hazardous material under this section by ranges, rather than a specific amount, pursuant to Section 4-8.402(a)(3)(i)(c), as long as those ranges provide the information necessary to meet the needs of emergency rescue personnel, to determine the potential hazard from a release of the materials, and meets the purposes of this chapter.

(d) The HMIS shall also include a carcinogen identification form which shall indicate the storage of any quantity of any carcinogen listed in Sections 5208 through 5215 and Section 5219 of Title 8 of the California Administrative Code, as amended.

(Added by Ord. 284, § 2, § 4, Ord. 309, eff. October 15, 1986)

The HMIS is a public record; however, the information contained therein is subject to trade secrets protection pursuant to Health and Safety Code Section 25511.

(Added by Ord. 284, § 2, § 5, Ord. 309, eff. October 15, 1986)

The City will require its permit applicants and permittees to fill out, in addition to forms required for City's own purposes under this chapter, standardized forms based on the application form and annual report form prepared by the State Water Resources Control Board as specified by California Health and Safety Code Section 25283.2, and City will forward these forms to the State Water Resources Control Board.

However, where any of the information required on such standardized forms is claimed by the permit applicant or permittee to be a trade secret, the permit applicant or permittee shall leave that portion of the form submitted to City blank, except to indicate the words "trade secret", and the permit applicant or permittee shall thereafter, within 10 days of submitting the incomplete form to City, submit the completed form including the trade secret information directly to the State Water Resources Control Board. City shall have no obligation to protect as a trade secret, any information which is furnished to it for forwarding to the State Water Resources Control Board on these standardized forms.
