• Divert stormwater away from disturbed or exposed areas of the construction.
• Install BMPs to control erosion and sediment and manage stormwater. 
• Inspect the site regularly and properly maintain BMPs, especially after rainstorms.
The Stormwater Pollution Prevention Plan (SWPPP)
Basic SWPPP Principles: 
• Revise the SWPPP as site conditions change during construction and improve the SWPPP if BMPs are not effectively controlling erosion and sediment. 
• Minimize exposure of bare soils to precipitation to the extent practicable. 
• Keep the construction site clean by putting trash in trash cans, keeping storage bins covered, and sweeping up excess sediment on roads and other impervious surfaces.
The Permit: Filing a NOI
• The Notice of Intent (NOI) must be filed for a permit.
7-day waiting period.
Permit coverage begins at end, unless otherwise notified.

Stormwater management is now almost everyone’s responsibility, because with NPDES II, more than 97% of all construction sites are covered under the new regulations.
To meet the requirements of NPDES II, a construction contractor needs a plan, a stormwater permit, and best management practices to prevent erosion from stormwater runoff.
The penalties for noncompliance can be severe. Fines can be up to $32,500 per day.
Or inspectors can shut down a site for non-compliance, which can cost thousands a day in lost production.
Take Wal-Mart as an example. One Wal-Mart construction site that was not in compliance was fined $100,000. 
One site.
Wal-Mart, to its credit, has looked carefully at the situation, and was actually a sponsor of the 2005 International Erosion Control Association meeting in Austin.
But with the right resource, complying with NPDES II can be easy and remarkably cost effective.
And Dandy Products is the ideal resource, because Dandy Products is the Stormwater Management Authority. Dandy Products provides the best management practices for temporary inlet protection during construction.
Dandy Products are lightweight and easy to install, easy to maintain and clean, easy to inspect, and easy to transport. They’re also convenient and cost effective.
Dandy Products can be used throughout a construction site on all types on inlets.
And with proper maintenance, they can be re-used, time and time again.
Dandy Products help keep your site in compliance so you can avoid fines and shutdowns. And they provide a “last line of defense” against sediment runoff by protecting inlets.
Unlike straw bales, silt fence, and wood frames, Dandy Products set up in seconds to reduce the time involved for implementing BMPs. And they keep contractors out of the pipe cleaning business.
Dandy Products reduce long-term costs. They protect aquatic life against damage from sediment, and their bright orange color demonstrate your compliance and environmental awareness.
Dandy Products are all produced in our factories, and they are designed specially for this use. In fact, they have been more thoroughly tested than any other competing product.
And through our partnership with Mirafi, we have the most extensive distribution network in the nation, so you have ready access to the products you need—when you need them.
The best practices. The best products. The best resource.
Dandy Products. The Stormwater Management Authority.
Let’s do a quick overview of the National Pollutant Discharge Elimination System, or NPDES.
NPDES can trace its origins back to 1972 and the Clean Water Act. The original program, NPDES I, was designed for large city stormwater systems and major industry.
The goal was to eliminate or control major point source pollution locations. NPDES included construction sites over five acres in size. Included sites required a plan for stormwater management.
NPDES II expands the coverage of the original regulations. It covers an additional 5,000 municipalities nationwide and covers all construction sites greater than one acre. This means 97% of all construction sites, tens of thousands of industrial facilities, and provides incentives to protect operations from storm water exposure.
To comply with NPDES II, a contractor must have a stormwater management plan, an NPDES II permit, and best management practices.
The Stormwaster Pollution Prevention Plan, or SWPPP, is comprised of principles including:
Diverting stormwater away from disturbed or exposed areas
 Installing BMPs to control erosion 
 Regular inspection to check and properly maintain BMPs.
The plan should be revised as conditions change or if the original plan is not effective.
 The goal is to minimize exposure of bare soils to precipation.
 And the site should be kept clean by putting trash in trash cans, keeping storage bins covered, and sweeping up excess sediment.
Once a plan has been established, the next step is getting a permit. This requires a notice of intent to be filed. At the end of a seven-day waiting period, permit coverage begins unless you are otherwise notified.
And getting a permit is simpler than you might imagine. The best way is to file online on the EPA website. This can cut up to 2 weeks off your waiting time. Online filing can also help you avoid mistakes, because the forms prompt you if you make an error.
Now, what’s a BMP. The EPA’s definition is that it is the “most common sense, cost effective plan to reduce storm water runoff on a case-by-case basis.”
BMPs are defined in EPA bulletins as non-structural and structural. Non structural includes minimizing disturbances. Structural BMPs include erosion controls like mulch and grass, or sediment controls like Dandy Products.
For construction, BMPs include inlet protection, plus other types of erosion control such as fences and blankets.
So for inlet protection, sediment control, and stormwater management, Dandy Products provide solutions for compliance with NPDES II.
You can learn more by getting this booklet from EPA. It can be downloaded from the EPA website.
Dandy Products provide inlet protection for the entire construction site. This includes field grates, flat and mountable grates, curb drains and inlets, and even sediment dewatering.
There are a variety of Dandy Products available for use. The Dandy Bag is for use with flat grates and mountable curbs.
Its unique patented design keeps silt, sediment, and debris out of storm systems, reducing or eliminating the need to flush or clean inlets.
The Dandy Bag is fabricated from a high-visibility orange Mirafi fabric. There are sizes to fit any inlet. And they are easy to install, maintain, inspect, and re-use.
The Dandy Sack has the same high visibility orange Mirafi fabric. It’s available in three sizes for flat grates. It also features optional oil absorbents, and can be used with Dandy’s curb blocking technology.
It installs easily, with no rebar. Internal straps hold the sack on the grate for added security, so that when you remove it, all the silt doesn’t drop into the inlet. The two-foot containment area is very manageable.
The Dandy Curb Bag is designed for use in curb and gutter inlets.
The unique patented design of the Dandy Curb Bag keeps silt, sediment, and debris out of storm systems. It’s designed to conform to the shape of the curb. It has a built-in overflow design, which reduces the need to flush or clean inlets.
It features the highly efficient orange monofilament Mirafi fabric, with sizes to fit any curb or gutter inlet. And it’s easy to install, maintain, inspect, and re-use.

There are sizes to fit any curb, and it can be used with optional oil absorbents. The Dandy Curb is easy to install, maintain, inspect, and re-use.
The Dandy Pop is a a unique design based on input from contractors who were trying to manage field grates. The Dandy Pop remains visible even when there’s heavy earth moving. With Dandyy Pop, there’s no more cumbersome silt fence or similar devices that can fall down or have infiltration points.
It’s easily visible to machine operators in the field. It pops open in just a second, and the dome design allows easy maintenance. There’s also a built-in overflow.
The Dandy Pop features Mirafi’s high-visibility fabric, and comes in standard sizes to fit any grate.
Here are some examples of the Dandy Pop on location.
Our Dandy Skimmer provides absorption capabilities in drains where oil or other contaminants may spill. It ties to the grate and floats for maximum performance. It’s cost effective security for problem drains.
For sites where there is a chance for petroleum product runoff, absorbents can be added to any Dandy product. These are water repelling, and are tested to work under stormwater conditions. When they become saturated with oil, they can be replaced.
Dandy also offers a dewatering bag to control sediment discharge in operations where water is being pumped. 
The dewatering bag easily installs onto a discharge hose, and it’s easier and more convenient than sediment traps or other alternatives.
It’s fabricated from Mirafi geotextiles, which are used to make dewatering bags hundreds of feet long, so they’re incredibly strong and effective. Dandy dewatering bags are available in three standard sizes so they can be used on virtually any job site.
We spent a great deal of time and effort designing Dandy Products so they are easy and fast to install, without hassles.
They can be installed in a matter of minutes by one or two workers, so they’re faster than homemade solutions.
The Dandy Bag, for example, simply slides over the grate. The weigh of the grate holds in it place.
Installation for the Dandy Sack is similar. Straps allow workers to easily handle installation.
The Dandy Curb bag also slides over the grate, and is held in place.
The Dandy Curb installation process is a little different. It is placed in front of the inlet, and gravel is used as ballast. 
Dandy Products are the most tested stormwater management products in the marketplace. We have invested in testing to determine what makes an inlet protection device perform properly.
An independent laboratory, , has conducted specific analyses of our products for strength, sediment capture, flow rates, and overall effectiveness.
This information helps us to continually improve, and we’re looking at even more testing that will tell us more. Ultimately, there may be specific fabric types that are matched to different soil types for optimum sediment capture and flow. 
More is now underway, and we’re excited about what we might learn.
So the future may offer you even more options of inlet protection, tailored to your specific job site.
We’re making the investment in this research because we feel this is our position as an industry leader.
And today’s Dandy Products have already been engineered for optimum performance to provide best management practices.
A key is Mirafi’s specially engineered Filterweave geotextile, which was created for strength, filtration, and effective water flow.
Compare the flow rate of silt fence material to that of Filterweave. You can easily see how it offers a better option for allowing water to flow while trapping sediment.
Here are more performance properties of Filterweave.
Dandy Products are designed and constructed to provide two layers of sediment control protection.
The top, or outer, layer of fabric stops most sediment.
While the second layer of fabric creates a compartment that can trap finder sediments and prevent them from entering the drain.
Our partnership with Mirafi gives us access to the largest geotextile distribution network in the nation.
There are over 300 distribution locations in North
America, which means products are readily available. And if you’re in a bind, we even have quick ship options to keep your site running.
Ten Cate Nicolon develops and produces functional materials that contribute significantly to progress in the industries that we serve. We operate in the United States, Europe and Asia. As a leader in the geosynthetics market, we are committed to offering a wide range of quality products through Mirafi.
