                         TOM J. BORDONARO, JR., MEMBER OF THE CALIFORNIA ASSEMBLY, has
         requested an opinion on the following question:

                         Are the operations of a composting facility subject to the waste discharge requirements of
         the Porter-Cologne Water Quality Act as administered by a Regional Water Quality Control Board?


                                                        CONCLUSION

                         The operations of a composting facility are subject to the waste discharge requirements of
         the Porter-Cologne Water Quality Act as administered by a Regional Water Quality Control Board; however,
         the board may waive such requirements if the particular circumstances so warrant.


                                                          ANALYSIS

                           The Legislature has enacted a comprehensive statutory scheme, known as the
         Porter-Cologne Water Quality Act (Wat. Code, §§ 13000-14958; "Act"), Footnote No. 1 to protect "the quality
         of all the waters of the state" (§ 13000). The Act is administered by the State Water Quality Control Board
         (§§ 13100-13176; "State Water Board") and by a Regional Water Quality Control Board (§§ 13200-13284;
         "Regional Water Board") in each of the regions of the state. The question presented for resolution is whether
         the operations of a composting facility are subject to the Act's discharge requirements as administered by a
         Regional Water Board. We conclude that they are.

                          In addressing the issues presented, we first note that compost is the product resulting from
         the controlled biological decomposition of organic wastes which have been separated from other solid
         wastes. (Pub. Resources Code, § 40116.) We are informed, for example, that at one such facility, the
         manufacturing process is carried out by having agricultural material placed in windrows 250 feet long, 8 to
         12 feet wide, and 5 feet high. Approximately 50 windrows occupy 20 acres of land, with the material being
         placed directly on compacted soil. The material is mechanically turned during the composting process to

         placed directly on compacted soil. The material is mechanically turned during the composting process to
         provide aeration and maintain appropriate internal temperatures in order to control pathogenic organisms.
         The final product is used as a soil amendment in agricultural operations and domestic gardening.

                           We also preliminarily note that a composting facility is subject to the permit requirements of
         an entirely separate statutory scheme, the California Integrated Waste Management Act of 1989 (Pub.
         Resources Code, §§ 40000-49650), administered by the California Integrated Waste Management Board
         (Pub. Resources Code, §§ 40400-40510; "Waste Management Board"). A person intending to operate a solid
         waste facility must first obtain a permit, either from a local enforcement agency or from the Waste
         Management Board (Pub. Resources Code, § 44001); permits issued by the former are subject to review by
         the latter. (Pub. Resources Code, § 44009.) A solid waste facility includes a composting facility (Pub.
         Resources Code, § 40194), and "solid waste" includes material which may be composted (Pub. Resources
         Code, § 40191).

                           Although the issuance of solid waste facility permits comes under the administrative
         purview of the Waste Management Board, the Legislature has declared that such permitting authority does
         not limit or affect the powers and duties of a Regional Water Board or the State Water Board. (Pub.
         Resources Code, § 40055.) The issuance of a permit by the Waste Management Board does not eliminate the
         requirement of obtaining a permit from a Regional Water Board for the same activities. (Pub. Resources
         Code, § 44009, subds. (b), (c).) The Legislature has attempted to ameliorate possible conflicts arising from
         such dual exercise of jurisdiction. Public Resources Code section 43101 provides in part:

                          "(c) It is . . . the intent of the Legislature, in enacting this chapter, and in making the
               necessary revisions to this division and Division 7 (commencing with Section 13000) of the
               Water Code by the act enacting this chapter, to accomplish all of the following:

                           "(1) . . . the [integrated waste management] board, the state water board, and the
               regional water boards shall retain their appropriate statutory authority over solid waste
               disposal facilities and sites. A clear and concise division of authority shall be maintained in both
               statute and regulation to remove all areas of overlap, duplication, and conflict between the board
               and the state water board and regional water boards, or between the board and any other state
               agency, as appropriate.

                           "(2) The state water board and regional water boards shall be the sole agencies
               regulating the disposal and classification of solid waste for the purpose of protecting the waters
               of the state . . , and the [integrated waste management] board and the certified local enforcement
               agencies shall regulate all other aspects of solid waste disposal within the scope of their
               appropriate regulatory authority.

                           ". . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

                          "(d) It is the intent of the Legislature, in enacting this chapter, and in making the
               necessary revisions to this division and Division 7 (commencing with Section 13000) of the
               Water Code, to ensure that the state minimum standards for environmental protection at solid
               waste disposal facilities are not reduced." (Italics added.)

                          With the relationship between these statutory schemes in mind, we return to the question
         whether the operations of a composting facility are exempt from the Act's waste discharge requirements as
         administered by a Regional Water Board. Generally, every person discharging waste (other than into a
         community sewer system) that could affect the quality of the waters of the state must file a report of waste
         discharge with the appropriate Regional Water Board. (§ 13260, subd. (a).) The Regional Water Board is
                ibl f         ibi        t di h          i      t (§ 13263 ) Whil           t           d     d t

         responsible for prescribing waste discharge requirements. (§ 13263.) While compost, as an end product,
         typically is an innocuous, indeed beneficial, organic material, the manufacturing process of creating compost
         is nonetheless a method of handling and treating solid waste. Footnote No. 2 We are informed that
         decomposable organic wastes may contain chemicals which could acidify affected waters or mobilize
         metallic pollutants from wastes or from the environment. Certain organic wastes contain high levels of
         nitrogen compounds that could raise levels of nitrates in surface or ground waters. Salts and microorganisms,
         including pathogens, may be released into the soil. In sum, the composting process presents the possibility
         that leachates Footnote No. 3 may migrate into the waters of the state. While compost, once created, may not
         pose a threat to the waters of the state, the biological processes involved in its creation may do so.

                         The sole basis for the claim that the operations of the composting facility in question are
         exempt from the requirements of the Act is the exemption language contained in an administrative regulation,
         California Code of Regulations, title 27, section 20090, subdivision (h), which excludes from a Regional
         Water Board's jurisdiction:

                           "Recycling or other use of materials salvaged from waste, or produced by waste
               treatment, such as scrap metal, compost, and recycled chemicals, provided that discharges of
               residual wastes from recycling or treatment operations to land shall be according to applicable
               provisions of this division."

         We reject the suggestion that the manufacturing operations of a composting facility fall under the exemption
         language of this regulation. "Recycling," as that term is used in the regulation, refers not to the manufacturing
         process of creating compost; rather, it refers to the use of compost as a final product. Under the plain wording
         of the regulation, the compost must first be "salvaged from waste, or produced by waste treatment" before it
         can be subject to "[r]ecycling or other use."

                           "Generally, the same rules of construction and interpretation that apply to statutes
               govern the construction and interpretation of an administrative agency's rules and regulations."
               (Industrial Indemnity Co. v. City any County of San Francisco (1990) 218 Cal.App.3d 999,
               1008.) Accordingly, regulations are to be interpreted by "giving to the language its usual,
               ordinary import and according significance, if possible, to every word, phrase and sentence in
               pursuance of the legislative purpose." (Dyna-Med, Inc. v. Fair Employment & Housing Com.
               (1987) 43 Cal.3d 1379, 1386-1387.) Here, the regulation exempts only the "use of materials
               salvaged from waste, or produced by waste treatment," with recycling representing one such type
               of use of a final product ("recycling or other use"). Footnote No. 4

                           Moreover, the regulation expressly requires that "discharges of residual wastes from
         recycling or treatment operations to land shall be according to applicable provisions of this division." It is
         this aspect of the composting process that the State Water Board and a Regional Water Board must regulate
         pursuant to the Act's provisions, monitoring and controlling the amount of leachates that might migrate into
         the waters of the state during the compost manufacturing process.

                          Although the operations of a composting facility are not exempt from the Act's waste
         discharge requirements, a Regional Water Board has the authority to waive such requirements "as to a
         specific discharge or a specific type of discharge where the waiver is not against the public interest."
         (§ 13269, subd. (a); see also Cal. Code Regs., tit. 27, § 20200, subd. (a)(1).) If the particular circumstances so
         warrant, the operators of a composting facility may obtain a waiver of the Act's requirements.

                           We conclude in answer to the question presented that the operations of a composting facility
         are subject to the waste discharge requirements of the Act as administered by a Regional Water Board;
         however, the Regional Water Board may waive such requirements if the particular circumstances so warrant.
