215Control of Imported Soils

215.01 Description.

This work includes controlling and testing materials transported to the site by the Contractor unless otherwise approved by RIDEM and LRSMM. Ensure that all work complies with the applicable rules and regulations of local, State, and Federal authorities, and provide certified documentation that unacceptable levels of hazardous waste are not present in the material. Refer to the Soil Management Plan for the Project.

215.02 Materials.

Ensure compliance with the following: • All laws applicable to the materials (hazardous and non-hazardous) transported to the site by any agents, officers, employees, visitors, and Subcontractors • Containment, storage, management, transport, and disposal of all soils according to all applicable environmental laws and permit approvals • Payment to applicable recipients for all penalties, expenses, costs, damages (including to natural resources, property, or persons), and liability related to the imported soils Test all imported soil used for backfilling, embankment construction, or topsoil, and ensure that the imported soil is free of contamination and meets RIDOT specifications. Provide the required testing in Subsection 215.03 before delivery of the soil to the Project site. The testing provisions for crushed stone, concrete sand, gravel borrow subbase, and special graded aggregate for shaping and trimming driveways or shoulders do not apply.

215.03 Construction Methods.

Samples, Tests, and Cited Specifications. Collect soil samples according to USEPA Publication No. SW -846, Test Methods for Evaluating Solid Waste, Physical/Chemical Methods. Ensure that the tests are performed by a National Environmental Laboratory Accreditation Program (NELAP) -accredited laborat ory approved to perform analytical testing in Rhode Island. Collect samples for each type of imported soils to be used on the Project based on the stockpile volume as follows: Volume of Import Soil Samples Per Volume Up to 1000 cu yd 1 sample per 250 cu yd 1001 to 5000 cu yd 4 samples for the first 1000 cu yd + 1 sample per each additional 500 cu yd Greater than 5000 cu yd 12 samples for the first 5000 cu yd + 1 sample per each additional 1000 cu yd.

Part 200 — Earthwork and Erosion Control August 2025

SECTION 215 — CONTROL OF IMPORTED SOILS 200-89 If imported soil will be derived from more than one source, attain the imported soil qualifications from each source according to the sampling frequency. Provide the geographic coordinates (latitude/longitude) of the imported soil sample location(s), and provide a general description of the soil type sample according to the Unified Soil Classification System (USCS) to the Engineer. Document the following laboratory analyses to ensure that the imported soil is free from contamination: Constituent Test Method Minimum Detection Level Volatile Organic Compounds (VOC) Method 5035 RIDEM Method 1 I/CDEC Semi-Volatile Organic Compounds (SVOCs) Method 8270D RIDEM Method 1 I/CDEC Total Petroleum Hydrocarbons (TPH) Method 8015D RIDEM Method 1 I/CDEC Polychlorinated Biphenyls (PCBs) Method 8082A RIDEM Method 1 I/CDEC Pesticides Method 8081B RIDEM Method 1 I/CDEC Herbicides Method 8151A RIDEM Method 1 I/CDEC SiRCRA Eight Metals Method 6010D and 7471B RIDEM Method 1 I/CDEC CDEC = Rhode Island Commercial Direct Exposure Criteria DEC = Rhode Island Direct Exposure Criteria Provide laboratory analytical reports to the Engineer for all imported soil to verify that the soil is free from contamination. Provide a copy of the associated lab report to the Department for review and approval. Failure to Maintain Control of Imported Soils. If the source material for gravel backfill, embankment, or topsoil that originates outside of the Project limits is placed on the Project and is found to be contaminated with unacceptable levels of hazardous waste or substances, remove and properly dispose of the contaminated material from the Department’s right -of-way. Secure the services of an environmental firm with the necessary experience and expertise to test the soil to ensure that the contamination has been removed. The selection of the firm is subject to the approval of the Engineer.
