N.Y. Comp. Codes R. & Regs. tit. 6, § 382.31 – Criteria for all disposal methods.

(1) Shallow land burial must not be used as a disposal method.
(2) Any disposal unit used for the disposal of mixed low-level radioactive and hazardous wastes or for the disposal of NARM waste mixed with hazardous wastes must meet the applicable requirements of Environmental Conservation Law, article 27, and regulations promulgated pursuant thereto in addition to the requirements of this Part.
(3) The disposal unit construction methods and techniques must not adversely affect the land disposal facility's ability to meet the performance objectives of sections 382.10-382.15 of this Part.
(4) In meeting the requirements of this Part, activities performed during the institutional control period may not be relied upon for more than 100 years.
(b) Design.
(1) The disposal units are integral parts of the disposal site and must function in concert with other features of the disposal site to ensure that the performance objectives of sections 382.10-382.15 of this Part are met. Any disposal method must be compatible with the following design requirements for the disposal site.
1. (i) The disposal site must be designed to complement and improve, where appropriate, the ability of the disposal site's natural characteristics to ensure that the performance objectives of sections 382.10-382.15 of this Part will be met.
2. (ii) The design of the disposal site must be compatible with the proposed methods of closure and stabilization and ensure that the performance objectives of sections 382.10-382.15 of this Part will be met.
3. (iii) The disposal site design features must be directed toward long-term isolation and avoidance of the need for continuing active maintenance after site closure and during the institutional control period.
(2) The performance of the disposal units must be capable of being defensibly characterized, modeled, analyzed and evaluated.
(3) The design of the disposal units must provide reasonable assurance of long-term stability. The time periods for such stability shall be: 100 years for disposal units containing only Class A wastes; 300 years for disposal units containing Class B wastes (alone or with Class A wastes); and 500 years for disposal units containing any Class C waste.

Any method used for a land disposal facility must meet the requirements of this section.
