This page provides draft guidance on preparing, amending, reviewing, or approving a Report of Disposal Site Information (RDSI) in accordance with Title 27, Sections 21600(b)(2) which is divided into two sections:

Please see the entire text of Title 27 Section 21600 which describe all nine parts of the required content.

Regulation (Title 27)Text of Regulation
Waste Types/Volumes - Describe the types of wastes accepted or proposed for acceptance. Estimated waste volumes should be presented, including current daily average and peak daily waste flows as well as a five-year projected waste flow. Specific
mention shall be made concerning the receipt of liquid, designated, special wastes or hazardous waste, if taken.


The information required by this section is critical for evaluation of the protection of public health and safety and the environment. Operational activities and special requirements in the Solid Waste Facility Permit may or may not be necessary based on the description of the waste stream and flow rates.

The following items should be discussed in the RDSI/JTD with regards to waste classification and management:

Waste Types anticipated for receipt at the facility, including a discussion of liquid, special, designated or hazardous wastes accepted or to be accepted:

  • Nonhazardous Wastes
  • Hazardous Wastes
  • Liquid Wastes
  • Asbestos Containing Waste (ACW)
  • Designated Wastes
  • Special Wastes

Waste Volumes anticipated;

  • Current daily average (tons/day) of waste received
  • Estimated peak daily flow (tons/day)
  • Projected five year waste flow (tons/day)

Waste Types

Descriptions of the types of wastes accepted or proposed for acceptance should be provided. Waste type descriptions should be categorized into the following groupings:

Nonhazardous Solid Waste

Nonhazardous solid wastes are described in 27 CCR 20220 as:

  • Putrescible and nonputrescible solid, semi-solid, and liquid wastes which include;
  • garbage, trash, refuse, paper, rubbish, ashes;
  • industrial wastes, demolition and construction wastes;
  • abandoned vehicles and parts thereof;
  • discarded home and industrial appliances;
  • manure, vegetable or animal solid and semi-solid wastes; and
  • other discarded wastes.


Should be included confirming that the above wastes do not contain hazardous wastes or contain soluble pollutants in concentrations that may exceed applicable water quality objectives. Expected wastes under this regulation must be listed to enable a thorough evaluation of the wastes to be received.

Hazardous Wastes

Hazardous wastes are defined as those wastes described in Title 22 California Code of Regulations, Article 1, Chapter 11, Division 4.5 (§ 66261.3 et seq.) and must be managed according to Title 22.

If hazardous waste is to be accepted, a listing should be provided of all individual hazardous waste types to be accepted. If a specific waste is to be accepted from more than one generator, the waste type need only be listed once.

Asbestos Containing Waste or “ACW”

The owner or operator of a Solid Waste Facility (SWF) that disposes of ACW in accordance with section 25143.7 of the Health and Safety Code on or after August 1, 1996, must file with the Enforcement Agency (EA) ACW amendments to the facility’s RDSI, as required in Title 14, Chapter 3.5, section 17897.15. These amendments should be consistent with other information contained in the SWF permit application package.

ACW amendments to an RDSI/JTD must be submitted for both existing and proposed SWFs disposing of ACW on or after August 1, 1996. The ACW amendments are a working document, which describe actual SWF and designated asbestos containing waste disposal area specifications and operations. They should describe the manner in which a SWF and designated asbestos containing waste disposal area is designed and operated to assure that potential public health, worker safety and environmental hazards associated with ACW handling and disposal have been eliminated or mitigated, and possible nuisances prevented.

The points listed below follow the organization of the ACW regulations and itemize the ACW-related information that must be filed with the EA in the formal or amended RDSI. The key words that appear in [brackets in Italics] are included to indicate the type of information being required.

ACW Design and Operating Requirements (14 CCR §17897.18)

(a) A survey plat which contains the location and dimensions of the designated ACW disposal area, pursuant to 14 CCR 17897.18(a). [Map]

Liquids or Semi-Solid Wastes

A discussion of the moisture content of the wastes to be received shall be included. The purpose will be to confirm that the moisture in the waste will be held below the moisture holding capacity of the landfill as described in 27 CCR 20200(d)? Wastes that contain more 50 percent liquids by weight may not be disposed of in a Class III landfill without an exemption from the RWQCB.

Special Wastes

If special wastes (as defined in 27 CCR § 20210) are to be accepted, a listing should be provided of all individual designated waste types to be accepted. If a specific waste is to be accepted from more than one generator, that waste type need only be listed once.

Medical Waste: The acceptance of medical waste should be addressed in accordance with 27 CCR § 20880.

Dead Animals: The acceptance of dead animals must be allowed by local regulations as discussed in 27 CCR § 20890. The EA must also determine and approve the type, number, location of disposal, and frequency of dead animals disposal of at the facility.

Other Wastes Requiring Special Handling: Other waste types may be in a physical form, which could create hazards or become a nuisance (i.e. powdery or dusty materials). In addition, wastes which have been made non-hazardous by virtue of a treatment process (ie autoclaving, fixation, solidification, etc.) may require special procedures to assure prior treatment was effective even though they may not require separate physical handling. Any wastes of this nature should be specifically identified in the RDSI/JTD. Procedures to prevent accidental acceptance of untreated wastes should be described in the RDSI/JTD sections describing materials handling and disposal site controls.

Designated Wastes

If designated waste (as defined in 27 CCR § 20210) is to be accepted, a listing should be provided of all individual designated waste types to be accepted. If a specific waste is to be accepted from more than one generator, that waste type need only be listed once.

Review Guide

  • Are the waste types proposed for acceptance consistent with those described in the supporting documentation (including other permits, JTD/ROWD, WDRs and CEQA documentation)?
  • Are there any wastes described in the general waste section, which should require special handling?
  • Are there wastes proposed for acceptance which require special handling? Are special handling procedures described in later sections of the RDSI dealing with materials handling activities?
  • Does the facility have a hazardous waste facility permit or a variance from DTSC for acceptance of any hazardous wastes?
  • Is the disposal of animals and other special wastes consistent with all other documents (CEQA, ROWD, WDRs, etc.) and local regulations.

Waste Volumes

Current or Estimated Daily Waste Average

Current or actual daily waste average volumes should be presented for review. The information should be clearly presented enabling the EA and CalRecycle to evaluate the data provided. All data should be presented in tons per day.

Estimated Peak Daily Waste Flow

Estimated peak daily waste flows should be presented for review. The basis for the estimation should be presented in a clear manner with sufficient supporting data to enable the EA and CalRecycle to conduct a review. All data should be presented in tons per day.


The estimated peak daily waste flow for X Landfill is Y tons per day. This estimate is based on past peak daily flow data, estimated increase in expected waste due to projected area growth and a 10% increase of unforeseen local occurrences. Information used to calculate the X tons per day rate are shown in detail in Appendix Z.

Estimated Five Year Projected Waste Flow

The basis for future waste flow projections should be described, including the source of data regarding population increase projections; waste generation rate increases; and waste reduction, diversion, or recycling rates. Projections should cover a minimum of five years.

Review Guide

  • Are the data consistent with other supporting documentation?
  • Are waste flow data clearly and concisely presented?
  • Are the assumptions behind the waste projections identified? Are they reasonable?
