Landfill

The Rapid City Regional Landfill is a Subtitle D facility permitted for operation by the South Dakota Department of Environment and Natural Resources. The landfill is located on 450 acres and has operated at this location since 1960. On an average day the landfill receives 400 to 450 tons of non-hazardous solid waste. In addition to household waste, the landfill receives construction and demolition debris, non-hazardous special wastes, and non-infectious medical waste for disposal.   

Petroleum Contaminated Soil
The landfill accepts petroleum contaminated soil after appropriate testing and approval. The petroleum contaminated soils are land farmed to volatilize and encourage microbial degradation of petroleum contaminants. Soil samples are taken at the end of treatment to confirm degradation. Once the soils have reached 100 ppm total petroleum hydrocarbons, the soil is used for daily and intermediate cover in the active fill area.

Large Scale Recycling – Yard Waste and Asphalt
The Rapid City Landfill prides itself on large scale, non-traditional recycling. It receives about 20,000 tons of milled and chunky asphalt and about 15,000 tons of yard waste per year. The asphalt is ground and then used on site for roads and compost pads, or sold to the public. The yard waste is ground, composted and screened to become a rich organic soil amendment. Both finished products are available for sale to the public. Recycled asphalt is sold for $25.00 per ton. All products are available at the Landfill to anyone.  Since they are sold by weight there is no minimum purchase required. Purchase is simple, pull on to the scale and let the attendant know which product you would like.  You may pay with cash, local check or credit card.

3/8 in Yard Waste Compost - $20.00/ton

Sludges and Sump Wastes
The Rapid City Landfill classifies sludge and sump wastes as special waste. These wastes must be tested for hazardous characteristics before receipt. The Rapid City Landfill is a Subtitle D landfill. It is permitted to receive non-hazardous solid waste. Chapter 74:27:13:18 of the Administrative Rules of South Dakota specifically addresses testing for hazardous waste. It says, "A person who generates a commercial or industrial solid waste must determine if that waste is a hazardous waste by the method specified in 74:28:22:01." This sludge is a commercial waste and therefore requires testing to prove it is non-hazardous prior to disposal at the Rapid City Landfill.
Chapter 74:28:22:01 references the federal regulations which define the identification and listing of hazardous wastes. In a nutshell, it says check for characteristics of the waste to determine if it is hazardous. Specifically:
  • Is it toxic? We determine this by having you test for eight metals that are considered to be toxic if they exceed the limits listed in the federal hazardous waste regulations. Shops that handle waste oils, brake repairs, bearing replacement,
  • Is it flammable? This is determined by having a flash point test performed on the sludge by a lab.
  • Is it corrosive? This is determined by having a lab check the pH.
  • Is it reactive? Will the sample react violently with water or air? Generally, sludges from shops would already have reacted at the generators facility if this were the case.
  • Under the solid waste regulations the landfill cannot receive bulk liquids and therefore, the landfill requires any sludge to pass a paint filter test to show it is not a liquid.
In most cases, unless some process in your shop has changed since your last test, you only need to do these tests once every couple years to keep your waste stream characterized and the landfill special waste files up to date. It is also in your best interest. If the Rapid City Landfill has an environmental problem at some point in the future, all waste generators become suspect and potentially liable for cleanup. Test results in the files can rule out those who are not guilty. With hazardous waste and most waste generation, the generator is liable for the waste from cradle to grave. Superfund sites have demonstrated this over and over. They seek out every potentially responsible party when it comes to paying for cleanup.  Special waste disposal requests from outside our service area must have the approval of the Public Works Director.
 
Guidelines For Disposal Of Sump Waste
Sump waste is classified as a special waste at the Rapid City Landfill. It must be tested for hazardous characteristics before disposal. Generally, sump wastes will not pass a paint filter test due to the amount of liquid. The only way to remedy this is to bulk the waste with a dry material such as dirt, bentonite, sawdust, etc., or dewater it. Dewatering is preferred. You will save money by dewatering the waste on-site. The water drained from the solids can be decanted back into your sump system and the solids can generally be disposed of at the landfill. Take samples for testing after the waste is dewatered or bulked.
 
Testing for Hazardous Characteristics and Liquid

You will need to have a representative sample of your sump waste tested for total metals including arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver; paint filter, pH, and flash point. Testing should be completed once every two years. These tests will cost about $185.00.
There is one environmental labs in Rapid City that can test this for you:Mid-Continent Testing Lab, 348-0111, Contact: Dean or Bob

The labs provide on-site sampling services at an additional cost or you can pick up the sample jars, ask for sampling instructions, and sample yourself. The testing results, information about your sump and services you provide, and a contact name and telephone number for your company, must be faxed to the landfill before disposal (Fax: 605-394-6843 Attn: Dennis). If the waste is not hazardous and passes the paint filter test, you will receive disposal approval by fax.
 
Waste Manifests
 
As the waste generator, you are required to manifest your waste disposal. A waste manifest provides a description of the waste, source name and address, hauler name and address, disposal facility name and address, and a signature block for a representative of each. When the waste arrives at the landfill, the scale attendant will sign and make a copy for the landfill files. The original will be given to the hauler with the disposal receipt. The Rapid City Landfill charges $59.00 per ton for sludge disposal. Direct your hauler to return a copy of the manifest to you with their invoice.
