What did you do differently?In key environmentally sensitive areas where it was not possible to cover the exposed earthworks immediately with topsoil, the slopes were sprayed with a dirt glue, this consisted of a powdered copolymer mixed with water.The product used was called Powdered Soiltac, this is an eco-safe, biodegradable, dispersible dry powdered copolymer.Once applied to the soil or aggregate, the copolymer molecules coalesce forming bonds between the soil or aggregate particles. As the water dissipates from the soil or aggregate, a durable and water resistant matrix of flexible solid-mass is created. This reduced the silt content within the water run off.

Please provide any supporting evidence pictures, graphs, figures, documents or other evidence.

Please ensure your justification is robust and that the issue has a proven track record: Provide your reasoning why you have assessed any of the selectivity criteria as highly beneficial: Note £ savings; Neutral Note time savings; NeutralNote impact on journey time reliability; NeutralNote benefits to health and safety; NeutralNote benefits to Highways Agency reputation: Reduced risk of silt run-off from the project and and visual discolouration of nearby watercourses to the public. Note contribution to sustainability/the environment. Reduced risk of silt run-off from the project and and visual discolouration of nearby watercourses .

Were any new risks introduced into the project as a result of the new way of working? Application of the product had to be undertaken in the dry and required a 48hr curing period prior to rain.

What prompted the iniative? To reduce high silt content water run-off from the extensive earthworks undertaken on the project.

Describe the circumstance that led to the issue. How does this initiative work and how was it put into practice?The A3 Hindhead Project requires extensive earthwork operations to be undertaken within an existing valley.There are several types of soil on site, all of which contain sand, silt and clay. (Upper Hythe beds A, B, C and D). During the earthworks operations the combination of exposed soil prior to topsoiling and periods of heavy rain have lead to heavy silt run off on the project.The silt run off can cause many problems, both environmentally and aesthetically. The sand particles are very fine and become suspended within the water for a period of 2-3weeks this limits the effectiveness of silt fences, straw bails and settlement ponds.

Soil-Sement® is an environmentally safe, advanced powerfulpolymer emulsion that produces highly effective dust control,erosion control and soil stabilization. Soil-Sement® providesexcellent bonding, cohesion, versatility, cost-effectiveness,environmental compliance and superior overall performance.

Soil-Sement®’s effectiveness results from the length andstrength of its unique polymer molecule formulation and thosepolymer molecules’ ability to bond with the surface materials.Its chemical structure is made of molecules attached inrelatively straight-linked chains and then cross-linked amongother chains or grids that may be 1,000,000 molecules long. Itis a true giant compared to the much smaller molecularstructure of oil, calcium, petroleum resin and asphalt emulsionproducts, which range from 100 to 10,000 molecules. As aresult, Soil-Sement® can be as strong as steel or as resilientas rubber.

Soil-Sement® is the cumulation of 24 years of focusedresearch and development, and unparalleled concentration onPM10, PM2.5, erosion control and stabilization solutions. Ityields proprietary one-of-a-kind polymer chemistrymanufactured to rigid quality standards utilized in combinationwith field experience in all industrial, commercial andmunicipal environments. The result is a performance andvalue combination that is unequaled by other chemical andpolymer products. As a result Soil-Sement® has been thestandard of comparison for all chemical types, includingpolymer products, since it’s introduction in 1978. Especiallytoday Soil-Sement® exemplifies the fact that all polymers arenot made equal.

In a comprehensive study just released by the U.S. ArmyResearch and Development Center of 12 non-traditionalstabilizers and three traditional types, SOIL-SEMENT®

(one of the non-traditional types) showed its potential toincrease the unconfined compressive (UC) strength of siltysand (SM) material under both “wet” and dry conditions.

The results verified that SOIL-SEMENT® polymer emulsionSIGNIFICANTLY improved the UC strength of the SMmaterial (58 percent in dry test conditions and 208percent in wet conditions). Except for cement andpolymers, other traditional and non-traditional stabilizersprovided no significant potential.

• The Soil-Sement® palliative appeared to exhibit a tolerance to the type of vehicular traffic of the Main Supply Route (generally heavy vehicles with both rubber tires and tracks). At the time of the evaluation (after 1 year), the Soil-Sement®

appeared to show some signs of wear but maintained its general integrity at the surface after receiving some heavy, abrasive traffic, particularly from tracked vehicles. The spalling observed appears to be predominantly from the aggregate being crushed or “popped” out of the surface, with only minor flaking of the Soil-Sement®-treated crossing.

In the most comprehensive study in the ironand steel industry performed for the UnitedStates Environmental Protection Agency,Soil-Sement® was compared to petroleumresins and asphaltic emulsions in controlledPM10 and PM2.5 testing involving unpavedroadways in the iron and steel industry.While all of the products performed at a highlevel of effectiveness immediately followingeach application, the true test came when theresults were once again compared 30 dayslater. Soil-Sement® maintained aneffectiveness rating within 10% of the initialapplication, while the effectiveness ofasphaltic emulsions and petroleum resinsdropped significantly.

DEMONSTRATIONKern County Road Shoulders

This report provided the initial results of ademonstration using Soil-Sement® as an alternativeto paving for fugitive dust control associated withunpaved road shoulders.

The USEPA mandated that the San Joaquin ValleyAir Pollution Control District commit to the rapidadoption and implementation of Best AvailableControl Measures (BACMs) in order to controlparticulate matter. One such BACM is the paving ofunpaved road shoulders. Kern County is but one ofeight counties in the Air District and the total milesof road potentially subject to the shoulder-pavingrequirement could exceed several thousand milesat a cost in excess of $100,000,000!

Midwest Industrial Supply, Inc. proposed ademonstration to the Air Pollution Control Districtto evaluate the cost and feasibility of usingSoil-Sement® as an interim and low cost solution tothe road shoulder paving requirement. During thedemonstration, Midwest Industrial Supply, Inc.stressed that the Soil-Sement® treated shouldersare expected to remain dust-free for 2 years!

Six weeks after application of Soil-Sement®, KernCounty Roads Staff returned to the demonstrationsite and found the following results:• The Soil-Sement® topical application provided a

hard stabilized surface and effectively eliminated dust on the road shoulders.

• Soil-Sement® provides a durable surface.

One of the conclusions from this

study is that shoulder maintenance

with Soil-Sement ® would keep

shoulders in better condition,

reducing the cost of shoulder paving.

Road Shoulder Stabilization

The San Joaquin Valley has one of the worst airquality problems in the nation and is one of a fewareas of the country classified by the USEPA as aserious non-attainment area for the federalparticulate matter air quality standard (PM10). Inresponse to the severity and longevity of theValley’s PM10 air quality problem, the USEPA foundthe Valley’s PM10 non-attainment area plandeficient and required the San Joaquin Valley AirPollution Control District to revise its plan andcommit to the rapid development andimplementation of Best Available Control Measures(BACMs).

For this demonstration the Fresno CountyDepartment of Public Works wanted to compareSoil-Sement® to slow cure asphalt, SC-250.Prominent differences between the two productsinclude:

• Soil-Sement® has no detectable emissions of VOC whereas SC-250 emits 400 lbs/mile of treated shoulder.

• Soil-Sement® is non-toxic whereas SC-250 has potential toxic and water quality implications.

• Soil-Sement® costs less than SC-250.

At slightly over 2 months after application,department personnel reported a number ofcomplaints about SC-250 track-out, and had toreturn to the site and apply a layer of sand toportions of the SC-250 treated shoulders.

“Effectiveness Demonstration of Fugitive Dust Control Methods for Public Unpaved Roads and UnpavedShoulders on Paved Roads,” Desert Research Institute, DRI Document No.: 685-5200.1F1.

Experiments were conducted from July toAugust in order to determine the PM10control efficiencies of different dustsuppressant materials on unpaved publicroads and unpaved shoulders along pavedroads.

In an initial survey, more than 60 specificsuppressant products were identified. Thesefell into categories of:

1) salts 2) asphalt or petroleum emulsions 3) emulsions of other materials4) polymers 5) surfactants6) bitumens 7) adhesives 8) solid materials, fibers and mulches 9) hydroseed vegetation

10) miscellaneous products

Conclusions were drawn with respect to: 1) efficiency and durability of each

suppressant2) fugitive dust emission rates 3) zones of influence of fugitive dust

emissions

For the unpaved roads, PM10 wasmeasured upwind and downwind of eachtest section. For the unpaved shoulderstudy, in addition to upwind and downwindmeasurements, instantaneousmeasurements from light scattering andturbulence sensors were made. Theefficiencies of Soil-Sement® exceeded 80%on average, during the final measurementperiod, 12 months after application. Of all ofthe other commercial products tested, themaximum efficiencies after a 12-monthperiod amounted to no more than 49%.

CONTRIBUTIONS TO PHASE I COMPLIANCE BY

SOIL-SEMENT ®:• Soil-Sement® will not affect pH levels. As

applied, Soil-Sement® is neutral pH.• Soil-Sement® does not contain oil or grease.• Soil-Sement® does not contain volatile organic

compounds or semi-volatile organic compoundsabove the regulatory levels.

• Soil-Sement®, when applied correctly and cured,will not increase BOD or COD.

• Soil-Sement® will not increase TSS (Total Suspended Solids) if applied properly. In fact, once dried and cured, Soil-Sement® will decrease the TSS.

CONTRIBUTIONS TO PHASE II COMPLIANCE

BY SOIL-SEMENT ®:Technical data is available showing:• The effectiveness of Soil-Sement® in binding

naturally occurring pollutants such as metals and arsenic to the soil, making them unable to enter into stormwater runoff.

• That Soil-Sement® will prevent dust from becoming airborne and settling as sediment in stormwater runoff.

DEPARTMENTS OF TRANSPORTATION NOW

RECOMMEND:• That methods of erosion and sediment control

should be considered “pay items” in the bids and specifications.

• That new road construction is usually funded approximately 80% by the federal government, and on-going maintenance is 100% funded by each state, therefore it is more economical to plan the erosion and sediment control into the initial budget.

• Part 91, Soil Erosion and Sedimentation Control, of the Natural Resources and Environmental Protection Act requires that soil and sedimentation control be considered throughout the development and delivery phases of a project, including planning, design, construction and maintenance.

• Of the products tested, only Soil-Sement® was successful in preventing roadbed deterioration (potholes, washboarding, rutting, and areas breaking up).

• Of the products tested, only the road segment using Soil-Sement® did not require regrading after6 months and prior to the maintenance application.

• Only Soil-Sement® prevented washing and excessive deterioration of the road surface following bad weather.

• Only Soil-Sement retained any practical ability for controlling dust after the 12-month period.

A county located in the high Mojave Desert region inCalifornia initiated a PM10 Dust Control Project toevaluate the effectiveness of various dust suppressantsfor unpaved roadways. The evaluation was conductedunder the direction of the Kern County Air PollutionControl District and coordinated through the CountyWaste Management Engineering Department. Theproducts tested included a pine tar resin, magnesiumchloride, calcium chloride, lignin sulfonate, petroleumresins and Soil-Sement®. Test sites were examined at3 months, 6 months, and 12 months followingapplication. The study found Soil-Sement® to be theproduct which continued to perform at the highest levelof effectiveness as both a dust and erosion controlagent.

Why Soil-Sement®

Beats the Alternatives forFugitive Dust Suppression:

As you know, there are many alternative methods offugitive dust control. Below are just a few...

WATERWater works well, but requires constant attention. (Forexample, Per Rule 403.1 of the South Coast AQMD -water must be applied at least THREE times a daywhen there is evidence of wind-driven fugitive dust.) Inaddition, water is most commonly applied by diesel-powered water trucks which themselves emit direct andtoxic PM and NOX.

WASHED GRAVELA uniform layer of washed gravel, while controllingfugitive dust temporarily, presents numerous otherproblems. Traction is inadequate and tire damage canoccur. Over time, dust emissions increase rather thandecrease due to steady traffic breaking down the gravel.Also, gravel is fairly expensive and subject to watererosion.

PAVINGPaving, while the best long-term solution to fugitive dustcontrol, is extremely expensive. In many applications,paving is impractical...the need may be temporary or thecost too extravagant.

Soil-Sement® is the only feasible, safe alternative to theabove-mentioned methods that has been verified bynumerous environmental agencies, including CalCert,California Air Resources Board and EnvironmentCanada.

Why settle for more expensive, time-consumingmethods when one application of environmentally safeSoil-Sement® lasts up to six months! Midwest IndustrialSupply, Inc. has the tested, certified choice to help youcomply with your water and air quality regulations...theonly choice...

Best ManagementPractices (BMPs)

Mandatory storm water permits and managementplans are being incorporated into the framework ofurbanized areas, making it imperative to addresswater quality in all aspects of development.Professionals, contractors and end users arestruggling to develop a systematic and logicalmethod for selecting the appropriate BestManagement Practice (BMP) to be integrated intothe various construction phases for their projects.

Best Management Practice is a technique,measure or structural control that is used for agiven set of conditions to manage the quantity andimprove the quality of storm water runoff in themost cost-effective manner. BMPs are designed toprotect and prevent new pollution.

With Midwest Industrial Supply, Inc.’sunderstanding of the types of structural BMPs andhow they interact with one another, we can provideguidance in obtaining the right mix for a specificsite. To ensure the maximum benefit is achieved,we evaluate your site so the most effective BMPfor the preconstruction, active construction andpost-construction phases is utilized.

The Preconstruction phase requires a carefulassessment of the specific site and a developmentof a clear understanding of what stormwatercontrols will be required by relevant stormwaterregulations, local ordinances and site planapproval processes. The Active ConstructionPhase deals with sediment containment systemsand vegetative techniques. Their roles are tocreate conditions for sedimentation, allowing soilparticles that are held in suspension to settle.Post-construction BMPs are techniques that canbe used to address flow quantity control of, andtreatment for, water quality through pollutionremoval in wet-weather runoff.

SOIL-SEMENT® IS THE ONLY CHOICE USED FOR ALLTHREE PHASES OF CONSTRUCTION:

Soil-Sement® will keep your operation

running smoothly and in compliance with

stormwater regulations

during all phases of construction!

Fugitive Dust EmissionsControl Plan

Regulatory agencies require operations to submitFugitive Dust Emissions Control Plans so that theamount of particulate matter carried in thesurrounding air as a result of man-made fugitivedust sources meets opacity, wind conditions andcontrol efficiency requirements.

Midwest has Fugitive Dust Emissions ControlPlans that are detailed to demonstrate theapplicable Best Available Control Measures orReasonably Available Control Measures that will beutilized and/or installed during all periods of activeoperations.

Our plans meet these three conditions:• All sources of fugitive dust emissions are

identified.• For each source identified, at least one of the

required control measures is implemented, or an acceptable justification statement is satisfied.

• If visible dust emissions are crossing the property line(s), then high wind measures are specified for immediate implementation.

We provide the following services so that yourorganization will avoid violations:• Maintain records to document the dates of

active operations, all applicable fugitive dust source types and the action taken.

• Retain such records for a period of at least 6 months.

• Provide trained on-site Dust Supervisors, as required by the South Coast Air Quality Management District

• Make such records available to the Executive Officer upon request.

Best Available ControlTechnologies (BACTs)

Best Available Control Technology is an emissionlimitation that will attain the lowest achievable emissionrate for the source to which it is applied.

Best Available Control Methods (BACM) andReasonably Available Control Methods (RACM) are alsoimportant techniques and procedures to limit emissionand/or airborne transport of fugitive dust from a site withsatisfactory results accomplished for temporary and/orextended suppression of PM10 emissions.

Soil-Sement® can be used to achieve Best AvailableControl Technology. Soil-Sement® is also considered tobe both Best Available Control Method (BACM) andReasonably Available Control Method (RACM).
