Twin Enviro Commercial Service provides numerous environmentally minded services

Twin offers environmental remediation services through partnerships with hazardous materials subcontractors. Twin features fast response times to contain, transport, and then dispose of transportation spills, tank leaks, and contaminated soils.
Disposing of special waste materials at Twin Enviro ensures that they will be properly contained at a facility with a good EPA record, and their harmful bi-products won’t wind up in our (or anyone else’s) air or water supply. Also, if we cannot accept a certain type of waste, we will provide information and resources on facilities that can (please, contact us for further details).

Our sister company, ACZ Laboratories is a full service environmental testing lab that employs close to 60 personnel and performs monitoring well, surface water, drinking water, radchem, soil, sludge and biota testing for clients world wide. The relationship with ACZ allows Twin to expeditiously and skillfully collect and transport samples for compliance testing to profile and approve waste disposal.

Asbestos Hauling & Disposal

Twin Enviro provides Friable and Non-Friable Asbestos collection and disposal. We can provide roll-off containers at your site for an abatement project, including 40 cubic yard closed top containers, if needed. We also have “taco bags” and 6 mil plastic bags for properly wrapping asbestos for transport.

Twin’s relationships with several abatement (asbestos removal) firms allows us to arrange for removal, transportation and disposal of Asbestos Containing Materials from jobs large and small.

• Twin cannot remove asbestos for you – you must hire an abatement firm.
• When disposing of asbestos at Twin Enviro, you must provide a completed asbestos report with manifest.

Compost Operations

Do you enjoy cooking? Making compost is very similar, although our ingredients are much less tasteful than the fresh ingredients you use in your recipes. Twin accepts food waste from customers, biosolids from the waste water treatment plant, horse manure from local horse enthusiasts, and wood debris from landscapers and residents. These ingredients are blended together according to a recipe and “cooked” in the environment for a determined amount of time.

Twin sends samples of the finished compost to ACZ Laboratories for analysis to ensure the finished product is free of pesticides and harmful bacteria.

The fresh ingredients used in your recipes can be recycled into compost used to grow new plants which create new ingredients for your recipes. 

E&P and Special Waste

Twin can accept Special Waste at its Landfills (Disposal Sites). These include Asbestos, Petroleum Contaminated Soil, Exploration & Production (E&P) Solid and Liquid Waste, used and out of date products and food, inks, toilet, sand and grease trap waste, and many other Special Waste materials.

A Waste Profile Form or Liquid Waste Profile Form must be completed and submitted for approval in advance for Special Waste collection or delivery to one of our Sites. Lab testing may be required.

A Manifest proving the waste was accepted for disposal at a properly permitted facility will be given to the customer and acceptance and payment for disposal of the special waste.

Contaminated Soil – Twin Enviro can accept contaminated Soil that passes a paint filter test (a USEPA test to determine if the waste is a liquid or a solid). Soils exposed to crude oil (benzene), drilling mud (barium), or other contaminants, usually must be lab tested, should be profiled, and must always be approved in advance. The Waste Profile Form for solids or the Liquid Waste Profile Form for liquids can be downloaded from the “Forms” tab.

Lab Sampling & Analysis

Twin Enviro can dispatch trained personnel to collect laboratory samples at your facility, and then forward them to our sister company, ACZ Laboratories, in Steamboat Springs, Colorado or the lab of your choosing. We can easily obtain sample containers to accommodate your parameter list. Remember, samples can produce problematic results from improper sampling technique or handling, wrong container or preservative use, cross contamination, failure to properly store and protect the temperature or light sensitivity of a sample, or not arranging for quick sample delivery to the lab to comply with holding time requirements.

Twin is capable of sampling monitoring wells, soil, sludges, bio-solids, sandtraps, surface water, wastewater and other waste streams. It can arrange for shipment to the lab, with custody documentation, preservation, and the ability to meet holding times.

ACZ provides a full range of metal, radchem, and organic testing, with a Class 100 cleanroom, and nearly sixty employees trained to provide quality data, on time.

Twin also provides dispatch service for lab samples by prior arrangement in Routt, Fremont, El Paso, Pueblo, Moffat and Las Animas Counties.

Landfill Operations

Responsible and sustainable landfill operations are more than just throwing trash in a big hole in the ground. Twin Enviro prides itself in strictly following local County and Colorado Department of Public Health & Environment regulations while developing Landfill cells.

Twin is continually working on new cell design, excavation, and construction to ensure your trash has an environmentally safe disposal site. Recycling is an integral part of landfill operations because it reduces the amount of trash that goes into the landfill.

Detailed Explanation of Landfill Process
  1. Engineered Design: The initial step in creating a new landfill cell is the engineering. Twin hires Colorado engineers to design the cell which entails a minimum separation from groundwater, designing the liner system, engineering storm water runoff, determining locations for groundwater monitoring wells and gas wells, and designing leachate collection sumps.
  2. Excavation: After the new cell is engineered, excavation commences. This entails removing all soils down to the engineered subgrade in preparation for the liner system.
  3. Cell construction: Each landfill cell is lined with protective layers to prevent any escape from the landfill. We start with 1.0 feet of clay compacted in 6 inch layers to a hydraulic conductivity of 1 x 10 cm/sec or less. On top of the compacted clay is a synthetic material called HDPE which is rolled out in sheets and welded together to create a waterproof seal. On top of the HDPE is a synthetic drainage layer to transport leachate to the sump. On top of the drainage layer is 16 ounce geotextile to protect the underlying liners. On top of the geotextile is one foot of sandy soil composite which further protects the underlying liners but allows liquids to pass through.
  4. Engineers again: Our engineers are on site throughout the entire process supervise the work and ensuring compliance with the engineered design. The engineers compile daily reports which are submitted to the Colorado Department of Public Health and Environment for approval. Once approved by the CDPHE and the County Health Department, Twin starts the process of disposing of your trash into the new cell.
  5. Disposal: After the new cell has been permitted, Twin begins adding the “fluff layer” of trash to the cell. The fluff layer is soft household trash that is the first layer of trash into the new cell. The fluff layer further protects the liners from being punctured or damaged. Once the initial fluff layer covers the entire new cell we can go into operation and dispose of construction debris along with household trash.
  6. Summary: The above process can take years to complete and Twin is continually working on new cell design, excavation, and construction to ensure your trash has an environmentally safe disposal site. In addition, the groundwater and gas monitoring wells are sampled and analyzed twice each year to ensure there has been no escape from the landfill into the environment.

Liquid Waste

Liquid Waste –Twin can also dispose of non-hazardous liquid waste at its Disposal Sites near Steamboat Springs/Craig and Canon City. Liquids are mixed with ash, wood chips or other solidification media in a large double lined and monitored basin, and after it is a solid, the mix is transferred to the working face and covered.

Liquid Waste must be profiled, laboratory tested, and approved in advance so Twin can be assured it is not hazardous. Most of these liquids cannot be put in the sanitary sewer. Liquids can be transported in your truck or ours. Typical waste streams include sand traps, exploration and production muds and drilling fluids, petroleum contaminated liquids, industrial and wastewater treatment plant sludges, ink, liquid truck spills and cleanups, out of date product, septic tank and portable toilet waste, and the liquids removed from re-refining used oil.

Drill Cuttings – Cuttings can be accepted as an exempt special waste at all our facilities, usually as a liquid waste. This waste is to be profiled, lab tested (if necessary), and always approved in advance. Download and complete the Waste Profile Form and call the Disposal Site you plan to use for additional requirements.

Material Recovery Facility (MRF)

What does a MRF do? The MRF will accept single stream recyclables into the facility, sort them into marketable categories, bale those categories into 20,000 lb. bales, and store the bales until sufficient quantities are available to transport to market where the recyclables are turned into new products.

You can dispose of all of your recyclable materials in one bin with out “getting your hands dirty”, we do the sorting for you! These recyclables do not end up in the landfill and that’s good news for all of us.

How does a MRF benefit our community and the environment? It facilitates turning recyclables into new, reusable products; it reduces the hauling of recyclables to large MRF’s in Denver and Grand Junction, thereby reducing engine emissions into the environment; it reduces the amount of large trucks on the road and the accidents and congestion resulting therefrom; and it allows Twin to accept recyclables from communities across NW Colorado. These all have positive impacts on the environment.

Milner Mall

Every year, hundreds of tons of otherwise useful building materials are sent to landfills because there is no mechanism to recycle these materials and make them available for reuse. This problem is especially prominent in the Yampa Valley, where the construction industry is one of the largest segments of the local economy. Frequent remodels, “scrape offs,” and new home construction projects are generating a tremendous volume of waste, much of it potentially reusable or recyclable.

The Milner Mall operates as a subsidiary of Twin Enviro’s Milner Landfill, and as a general rule, we encourage the public and businesses to de-construct buildings rather than demolish them. We offer a place for owners to donate salvaged materials so they can be reused, which keeps materials out of landfills and saves natural resources. Plus, you can save yourself the extensive disposal fees, win-win!

We then offer the salvaged materials for sale to the public at a discounted rate. The income from these sales is used to fund the organization.


Mobile Safety Showers

Mobile Safety Showers are portable, trailer mounted, fully enclosed and conform to ANSI Spec Z358.1.T. These Emergency showers are Freeze Protected when connected to a power source or can be run by an included Generator.

This equipment is excellent for Exploration and Production of Oil and Gas. It is often used when Fracking Units are designed for dependability at remote sites. Rugged construction includes steel exterior and roof boughs and insulated walls and piping.

Features easy setup, and can be towed with a full 400 gallon tank of water. We train your crew in operation and care on a set schedule. Full maintenance is included in the rental price. Available by the day, week, or month.

Portable Toilets

Portable Toilets are available in all our market areas. We can service construction sites, special events, drilling sites and other applications. Toilets can be on the ground or trailer mounted. Handicap toilets and hand wash stations are also available.

Pig Cleaning & Hydrostatic Testing

This service is now available at our Moffat and Fremont County locations.

Pipeline pigs are devices placed inside a pipe that traverse the pipeline. They are used in hydrostatic testing and pipeline drying, internal cleaning, internal coating, liquid management, batching, and inspection. In hydrostatic testing, the pipeline is filled with water (or other test liquid), removing any trapped air.

The pig is inserted ahead of the fill point, and liquid is pumped in behind the pig to keep the pipe full and force air out. Pigs then remove the test liquid and are used to help dry the pipeline.

Recycling Operations

Twin is the recycling services leader in NW Colorado: Cardboard, paper, plastics, bottles, aluminum, metals, food waste, wood and other organics are all put to beneficial reuse by Twin. How many other trash and recycling haulers can say that? 

24/7 Spill Response

Twin Enviro can respond to your spill or cleanup needs. We routinely work with “HazWoper” trained first responders based in Denver and Colorado Springs, and can call them in if needed. Because we operate our own disposal sites, and have roll-off equipment, vacuum trucks, submersible pumps and other cleanup equipment, we ask that you call the appropriate 24/7 cell phone numbers on the CONTACT page.

Past projects include train derailments, truck and fuel tanker crashes and spills, stationary and frac tank leaks and cleanups, and semi-trailer cargo spills.

Tank Cleaning

We are certified and experienced in CSE for Cleaning of Frack Tanks, Truck Tanks, Tanker Washouts and Above-Ground Storage Tanks, so that only trained personnel enter into and work on your equipment. We use ventilation equipment, air quality monitoring instruments, and a “hole man” for safe operations.

For Frack and other Tanks that are movable, we recommend they be brought to one of our sites. Twin’s tank washing is efficiently performed in a completely lined and fully contained basin so that the tanks’ contents and used washwater is not discharged into the environment. The used contents are carefully removed from the bottom of the basin and the sump, filtered, and disposed of in full compliance with liquid and/or solid waste regulations.

Twin has experience with other CSE projects including manholes, “pigging “ equipment, and the removal, solidification and disposal of liquids from cleanups and spills.
