EPA Emissions Regulations (Tier 4) and Compliant Systems

Wednesday, April 18th, 2012

Meeting the growing need around the world to replace and expand sewer and clean-water infrastructure is tough, especially when you take into account the new United States Environmental Protection Agency (EPA) Emissions Regulations, also known as Tier 4. The EPA Tier 4 standards are designed to reduce emissions by as much as 90 percent or more, according to the EPA.

Thankfully, there is a solution: the AXIS guided boring system by Vermeer.

This trenchless system eliminates many of the steps associated with traditional opencut installation techniques, speeding up installation and requiring fewer operators.
“This new system came to market because methods used in the past were rudimentary and slow,” says Ryan Erger, product specialist for the AXIS system. “We integrated several technologies into one system that allows contractors to install underground pipeline with extreme accuracy at a fast rate, all the while helping to reduce the environmental footprint.”

Benefits of the Axis System

  • The system integrates a closed-circuit camera into the drill head, allowing the operator to constantly monitor the drilling process.
  • The excavated material is removed by a high-powered liquid-ring vacuum driven by a John Deere PowerTech PVX 6068H Interim Tier 4/Stage III B engine. These engines feature cooled exhaust gas recirculation (EGR) for NOx control and an exhaust filter for reducing particulate matter.
  • Excavated materials are collected in a vacuum tank, eliminating the hassle of manually handling the spoils in the launch pit.

“The cooled EGR and exhaust filter technology approach provides a simple and proven solution requested by our customers,” says Doug Laudick, manager of product planning at John Deere Power Systems. “We believe cooled EGR provides our customers with the best value for Interim Tier 4/Stage III B.”

If you have any questions about Tier 4 Compliant Systems or if you have a construction project that you need completed right the first time, please contact Reliable Contracting by calling 410-987-0313 or visit our website.

EPA Emissions Requirements for Construction Equipment

Tuesday, April 10th, 2012

In 2004, the United States Environmental Protection Agency (EPA) set new emissions standards – Tier 4 Standards – for non-road diesel engines. These standards are designed to reduce emissions by as much as 90 percent or more, according to the EPA.

Since 2004, construction equipment manufacturers have been working diligently to meet these Tier 4 standards by developing new, greener solutions including:

  1. Selective catalytic reduction (SCR)
  2. Cooled exhaust gas recirculation (CEGR or EGR)

Many construction equipment manufacturers are using SCR, CEGR or EGR, or a combination of the two to meet Interim Tier 4 standards.

 The Difference Between SCR and CEGR/EGR

-SCR is an after-treatment only system. It creates a chemical reaction by adding diesel exhaust fluid (DEF), transforming the NOx into nitrogen and water, which occurs naturally in the atmosphere.

-In a CEGR system, exhaust gases are cooled and blended with fresh air, then returned into the cylinder. This helps lower combustion temperatures and drastically reduces NOx. However, the cooler combustion temperatures produce higher PM levels, which require an after-treatment diesel particulate filter (DPF) system.

Tier 4 technologies will not add any complexity to the operation of construction machinery. In fact, operators should find it easy to check DEF levels on SCR-equipped machines, and to check the diesel particulate filter on machines featuring the CEGR technology.

If you have any questions about EPA Emissions Regulations (Tier 4) or if you have a construction project that you need completed right the first time, please contact Reliable Contracting by calling 410-987-0313 or visit our website.

Subsurface Utility Mapping

Tuesday, April 3rd, 2012

One of the most critical bits of data needed before any urban or suburban construction project can begin is the whereabouts of underground utilities. Contractors must be aware of water trunk lines, sanitary tap-ins, power lines, and gas line for several reasons.

  1. Contractors need to know where these utilities are in order to tap into them.
  2. Contractors need to know where these utilities are in order to avoid them during excavation and other intrusive construction activities.

If these utilizes are not located before a construction project begins, the results can be extremely damaging and costly.

For precisely measuring underground utilities, several different tools are needed, including:

Metal Detectors: These devices can locate utilities and compute depths by using magnetic field measurements.

Gradiometers: These devices measure magnetic field gradients (changes) instead of total field strength.

Optimal Ranging’s Spar Utility Locator (FieldSens): This new technology computes the effects of ground conductivity and field distortions in real time, combining this information with GPS map utilities in 3D.

Acoustic Technologies: A sensitive acoustic reader is used to read background sounds, such as water flowing. This is perfect for locating leaks or other damage in water lines or other lines with a flow.

Ground Penetrating Radar (GPR): This method utilizes radar pulses to image the subsurface, producing a geological cross-section of the soil based on the electrical properties of the ground. GPR uses electromagnetic radiation in the microwave band of the radio spectrum, and detects reflected signals from subsurface features.

As you can see, there are several options available to contractors to help find the locations of subsurface utilities.
