At a waste facility, what can be done to be a good neighbor within the community you serve?
This article appeared in the May 2019 edition of Waste Advantage Magazine
Transfer stations and material recovery facilities (MRFs) serve important functions to the greater community. They serve as a means to more efficiently transport municipal solid waste (MSW) for disposal and recover materials for recycling to minimize what is sent to the landfill. From a high level, they exist as purely positive forces with important functions. Why then, are they relegated to the far corners of industrial parks or adjacent to closed landfills? This issue relates to the complexities of managing the potentially negative impacts these facilities can have on their neighbors and the community as a whole. By better understanding the impacts your facility can have on the larger community you can better address them or use education to build a greater understanding and appreciation for the realities of your business. The impacts can be grouped into several categories: Vectors, Odors and Dust, Wind-Blown Debris, Environmental Concerns, and Traffic.
Any facility that receives solid waste, single stream recyclables or source separated material has as issue with vectors in one way or another. Vectors as a term covers nuisance animals that can carry disease. For solid waste facilities, this mostly deals with mice, rats and birds. There are several operational best practices to help minimize these populations. For the mice and rats, keeping the floor clean is important. In addition, designing a facility with minimal space to create homes can help stop a colony from getting a foothold. As a best-practice, a local pest control company may be engaged to set up bait block stations to keep the population of these low. Birds, on the other hand, can pose a difficult challenge. The birds will often roost in the roof rafters, and their waste can become a large issue. There are several strategies that can be effective in dealing with this, depending on your building type and the type of bird you are attempting to discourage. Bird wire—a wire that is strung across tipping aprons and similar areas—discourages the birds from nesting in the areas it is strung. In addition, you can install bird netting on the inside of your building to keep the birds from roosting in your ceiling. Another approach that can be effective is using air noise makers to disturb the birds. You must take proactive action to keep these vectors under control, as their populations not only impact your facility, but your neighbors who will also pay the price if you do not address this.
Odors and Dust
The issue with odor and dust in transfer stations and MRFs can be greatly minimized through smart facility planning, operations and a few remediative approaches. When you are designing a facility, it is important to site the primary tipping bay doors away from the prevailing winds. In addition, high-speed doors can be installed on all exterior doors.
This Transfer Station was oriented on this site to have the unloading doors facing south. This positions them away from the sight-line of all adjacent odors. Having the rear of the building near the entrance also allows for a preferred traffic pattern and, aesthetically, leaves a fairly attractive wall visible to traffic. Also, the building will blend into the surroundings, helping to keep attention away from the facility. Visit this project on our website for more information!

Focus: CNG Conversion at Existing Facilities,
New Staff Biographies
Safety, code compliance and cost effectiveness should all be central considerations when upgrading a facility.
This article appeared in the February 2019 edition of Waste Advantage Magazine
Converting a fleet to compressed natural gas (CNG) can make a lot of sense to reduce fuel costs. Typical considerations toward making this decision include the cost of the new vehicles as well as the fueling infrastructure. An often-overlooked component, that is essential for a fleet CNG conversion, is the cost to modify the existing shop facility to ensure those new vehicles can be serviced in a safe and code compliant environment. It is essential to understand the activities that occur in the shop as they have a direct impact on the CNG retrofit building modifications.
Existing Shop Typical Improvements
As the existing shop is assessed, the first question should be about what might be required for it to be CNG compliant. While a qualified engineer or specialty consultant should be engaged to perform the detailed analysis and scoping, there are several elements that will likely need to be provided, as well as several items to avoid.
The existing ventilation system will likely need to be upgraded to afford more air changes per hour. The shop (if it is heated) is likely heated with a gas-fired unit or radiant tube heaters. These are typically not compatible with a CNG shop and will need replacement.
The height of the shop has a direct impact on the ventilation requirements. If the shop is shorter than 20′-0″, it may not be entirely viable for a CNG retrofit.
It is likely that the existing facility does not have a gas detection system. One may be required by the local Authority Having Jurisdiction (AHJ).
The walls that separate the shop from the administration offices will be required to be two-hour rated for a CNG Shop. If the current walls are not rated, upgrading these can be costly and disruptive to operations.
Look up at the ceiling and down at the floor. If there is any wiring or conduit in the areas within 18″ of the roof or the floor, it will need to be upgraded to Class 1, Division 2 rated.
This is not an exhaustive list of where all changes need to be made, but it is meant to help illustrate how the CNG retrofit work can impact many different areas of the shop. With a better understanding of areas where upgrades will likely be necessary, the next step will be to work with a consultant to perform a detailed analysis of the facility to better define which of the potential upgrades the facility will need to begin servicing CNG vehicles.
Existing Shop Classification
The assembled team should start the shop conversion analysis with a detailed review of the existing shop and what activities are performed there. The goal will be to determine whether the facility will be classified as a Minor Repair Shop or Major Repair Shop The terms ‘Minor Repair Shop’ and ‘Major Repair Shop’ are designations in the code that determine the standards the shop needs to meet, depending on the work that will be performed there:
- Minor Repair Shop: This includes service activities that do not impact the fuel system or generate heat in excess of 750° F (welding, grinding, etc.). It does include brake repairs, tire work and PM activities.
- Major Repair Shop: These include areas where there will be welding, vehicle body work or engine overhauls. Fuel system work may also be performed here.
Our client needed a new facility with a CNG compliant shop to meet local contract requirements. The new facility has (6) maintenance bays, (1) lube equipment & storage bay, (1) wash bay and an office area to accommodate all the drivers, training, locker rooms and operations team. It also has a second floor for storage and future expansion.
