Not all polymers are created equal

Posted in Dust Control, Environmental Certification/Independent Testing, Environmental Services Industry, Erosion Control, Soil Stabilization by Bob Vitale

Simple statement I know. Just take a look at the images below. Talk about a picture being worth a thousand words! Here’s the quick story. The first image was the customer’s work done with Midwest product. This was a Midwest customer for about ten years. The second image is the same project/customer done with a competitive product this year. The customer put this out for bid, specified our product or equal, they received a lower bid price, but really did not realize what they were buying – in part because the vendor provided them with what was thought to be credible information but was in fact intended to mislead. I’ve written blogs on “Buyer Beware” and this is again another example. All the cliché’s… you get what you pay for… clearly an issue in the dust control industry. When you put a project out for bid, you must be sure you are receiving estimates/prices that not only completely match regarding the formulation of the product, but that the company you are buying from guarantees that you will be satisfied with the result.

Solar Guidelines released in Arizona

Posted in Dust Control, Environmental Services Industry, Soil Stabilization by Bob Vitale

Environmental Solutions will support the building and maintenance of these important projects.

Great to read about the detailed research that is taking place to develop best practices for Solar Energy Developers, which is so important to the energy alternative solutions this country so desperately needs. The Dust Control, Soil Stabilization and Erosion Control Industry will play a major role in helping our country not only build these new energy plants with a commitment to mitigating negative environmental impact during this process, but maintaining these plants as well with a focus on “green” and safety.

Building these projects requires construction roads, service roads, heavy equipment movement as well as post construction maintenance to keep Solar panels and wind farms in optimum condition. It is critical that these projects use best green practices during the construction and maintenance process and do not overlook unintended consequences which could harm the environment if not planned properly.

Guidelines for Solar Development in Arizona

The Arizona Game and Fish Department, March 12, 2010

On March 12, 2010, the Arizona Game and Fish Department (“AGFD”) released finalized guidelines for solar development in Arizona (“Solar Guidelines”), the objective of which “is to assist energy developers in identifying potential impacts to wildlife and wildlife habitats from their proposed development and potential alternatives to avoid, minimize, and/or mitigate for these negative impacts.” The AGFD encourages local governments and permitting authorities to integrate the recommended study proposals described in the Solar Guidelines. The document is organized around five basic project development steps:

  • Wildlife Protection Regulations
  • AGFD Regulations and Review
  • Gather preliminary information and conduct site screening
  • Identify potential impacts to wildlife
  • Mitigation

The Solar Guidelines were compiled by the AGFD employees and have not undergone any external public review or input from the solar energy industry. It should be noted that some of the information contained in the Solar Guidelines was taken from the AGFD’s wind guidelines. In light of the fact that county officials often defer to the AGFD in matters of wildlife concerns, special attention should be given to the section of the Solar Guidelines focused on “Avoiding or Minimizing Impacts” and the recommendations contained therein.

In addition, AGFD identified several areas in which information regarding the impacts of utility-scale solar development on wildlife and habitats is lacking. Specifically, AGFD believes that research is needed on the following topics:

  • Determine the “effective footprint” of utility-scale solar development so mitigation strategies can be implemented at the spatial extent of the impact.
  • Need to determine the potential effects of a proposed solar project on the demographics of
    select wildlife species.
  • Evaluate the alteration of vegetation and micro-climate adjacent to solar facilities.
  • Identify the impact that utility-scale solar development has on wildlife corridors.
  • Evaluate the movement and behavior patterns of select wildlife species (e.g., ungulates,
    grassland passerines, raptors) pre- and post construction
  • Examine the impacts to migratory birds and bats.
  • Develop mitigation strategies to reduce the impacts of water impoundments associated with
    solar facilities.

It’s time to reduce import duties and non-tariff barriers

Posted in Dust Control, International, Soil Stabilization by Bob Vitale

on Environmental Goods and Services

The time right for this effort. I know first hand how the international market is seeking solutions to environmental challenges regarding dust control and soil stabilization for a multitude of major projects around the world. We track the visitors to our website and international visitors have become a significant percentage of traffic. These visitors are not only spending time on our site learning about our products and services, but also requesting for quotes on a variety projects that need environmentally-friendly solutions. We have active projects in India, Egypt, Spain, Italy, South Africa, Saudi Arabia and the UK to name a few, so the time is certainly right to help both US companies and international markets expand their relationships and help provide environmental goods and services at lower costs and efficiencies.    

Below is a recent article outlining the process the US Trade Representative is moving on.

The Best Choices Will Not Cost, They Will Pay

Posted in Dust Control, Environmental Services Industry, Erosion Control, Soil Stabilization by Bob Vitale

ReGeneration Productions is a company whose mission is to “create educational media that communicate the ideals and practice of urban sustainability.”  Their first endeavor, Mission:Sustainable, gives a “green” makeover to individuals needing to integrate sustainable practices into their lives. In a recent blog post titled “Working soil so that soil works for us,” ReGeneration states that they believe that “sustainability comes down to knowing that each choice we make has a ‘cost.’ The true ‘cost’ is a combination of the economic, social and environmental costs set against the offsetting benefits associated with each choice we make.”   This concept has interesting value to the commercial and industrial segment of our earth community.

As stewards of clean air, clean water and human health, our mission is to help make improvements in the work processes used by industrial customers that deliver economic, social and environmental benefits that exceed the cost of those improvements.  The main areas of our work revolve around dust control, especially pm10 and pm2.5 health risks; sediment and erosion control, which pose risks to water and aquatic life; and stabilization that provides the social benefit of smooth, pothole free roadways for area residents while delivering improved business results and operating performance.

The amazing thing is that this is absolutely, positively doable today. There is so much improvement possible with the choices we make in the commercial and industrial arena while providing significant economic and social and environmental returns that we often say, “the best choices will not cost, they will pay.”

Buyer Beware

Posted in Dust Control, Environmental Services Industry, Industry Watchdog, Soil Sement, Soil Stabilization by Bob Vitale

I would like to share an interesting story with you. It represents an example of why I believe independent testing of company claims is very important for the purchasers of products from companies within our industry – during the bidding stage, and then again during the delivery stage.

For many years we have been supplying a customer with their requirements for a dust palliative and soil stabilizer. Our multi-year contract just expired and the user has issued a notice of solicitation for current bids to fulfill their requirements. Their solicitation included a detailed performance requirement for the product to pass CBR lab testing for a specific soil type to meet the standards for the customer’s needs. The specification matched our specific product, which they have been using for many years.

In the bidding, a competitor quoted a price approximately 20% below our quoted price. Part of the competitive vendor’s bid information included marketing and test data to prove that their product was equal to the product called for in the specification.

Shortly after the competitor was awarded the new multi-year contract for the delivery and installation of their brand name product, based on being the low bidder, they began communicating with producers of the basic raw materials stating they had just received a multi-year contract and needed to source significant volumes of a non-prime polymer emulsion. Within these communications there was no product chemistry specification that might indicate that what they were trying to source would meet the requirements as called for by the purchaser’s specification.

So here is the issue; since testing and documentation for the specification requirements is typically only required at the bidding stage, and product sampling is NOT required at the delivery stage to assure the exact product specified in the bid is being delivered, the bait and switch can take place and the customer will never know.

It will take due diligence on the part of the customer to catch this bait and switch activity. It will also take significant due diligence to confirm that the environmental soundness of whatever is actually delivered and installed on public roadways is in fact what was represented.

We know that price is an issue and customers need to assure their constituencies that they have done everything possible to obtain the best product solution for the lowest price. We also know customers do not want to “buy price” and close their eyes to product deficiency and possible environmental issues.

This is why it is in the best interest of both the community of users and principled industry leaders to expose such bait and switch activities. This is needed for both the protection of people and the environment in which these products might be used.

Environmentally Responsible Construction

Posted in Soil Sement, Soil Stabilization by admin

Last year, our Soil Sement® product was used in the construction of the trailhead to the nation’s largest urban nature preserve, Scottsdale’s Lost Dog Wash Trailhead.  The project’s mission statement for the access areas was “to develop environmentally responsible public access areas that borrow from and blend into the natural desert landforms and landscape of each specific Preserve access location.”  A critical element of achieving their mission was salvaging and stockpiling the top four inches of native soil and native “desert pavement” cobble within the limits of disturbance for later redistribution. This allowed the project’s top-dressing to seamlessly integrate into the adjacent coarse and rugged desert floor. In addition, the parking lot areas and vehicular drives were constructed of Soil Sement stabilized decomposed granite, in lieu of traditional paving materials, to increase percolation and minimize surface runoff and heat gain. The Soil Sement-stabilized granite parking areas and trail surfaces utilized screened site soils to match the adjacent colors and textures of the desert floor.

This site was recently awarded the top Honor Award by the American Institute of Architects, Western Mountain Region and also honored by the American Society of Landscape Architects.   The Professional Awards Jury 2008 comments capture the achievement of this collaborative effort of the landscape architect, architect and the Preserve staff:

“One of the best examples of environmental stewardship we’ve seen this year. The landscape architect is commended for reusing the plant material. The design is regionally appropriate and moves through the landscape with real restraint.”

Our contribution with Soil Sement was lead by EarthCare Consultants and its managing partner Marty Koether. Marty and EarthCare have lifelong experience in paving and 15 years  in stabilization utilizing native materials and innovative stabilization products.

The Lost Dog Wash Trailhead is a real demonstration of the use of modern technology to support the natural environment which is a vital lifestyle and conservation decision and the protection of fragile desert ecology.
