There are a number of concepts that play a key role in managing stormwater pollution prevention plans (SWPPPs) for any construction site or similar area, and the realm of storage is often important here. Storage of certain items, particularly chemicals or any others that may lead to runoff and possible contamination of nearby areas, is a vital consideration for any SWPPP approach.

At Silver Leaf SWPPP, we're happy to assist clients around Utah with every element of the SWPPP process, from SWPPP inspections and documentation to risk management, dewatering, street sweeping and more. Here are some of the reasons why storage is so important on jobsites where SWPPP programs are in place, plus some examples of how to store certain materials or products to ensure no compliance issues arise in this area.

Why Storage is So Important in SWPPP

Before we get into some specific examples of storage approaches that are often used in SWPPP programs, let's talk a bit about why this element is so crucial. Here are several key themes to consider:

  • Preventing Runoff: As noted above, the primary purpose of storage when it comes to SWPPP plans is preventing runoff from certain materials or products. This may include chemicals, oils, or any other items that could potentially contaminate nearby areas if they were to be carried away by heavy rain or other weather events. Proper storage techniques can help prevent this from occurring, keeping the jobsite and surrounding areas clean and free of harmful materials.
  • Compliance: Another reason why storage is important for SWPPP programs is simply compliance with regulations. Most construction sites are subject to a variety of federal, state and local regulations regarding pollution prevention, and proper storage is often a key component of these requirements. By storing materials in the correct manner, construction companies can avoid potential fines or other penalties that could result from non-compliance.
  • Safety: Of course, another key reason for proper storage techniques is safety - both for workers on the jobsite and for the surrounding community. By storing materials in the correct manner, construction companies can minimize the risk of accidents or injuries occurring on their site.

Now let's look at some examples of common materials on jobsites and how they should be stored with SWPPP compliance in mind.

Building and Site Materials

When it comes to general building and site materials, there are a few key considerations to keep in mind. First, it's important to store these items on an impermeable surface - such as plastic sheeting or asphalt - to prevent them from coming into contact with the ground and potentially causing contamination.

Additionally, materials should be stored well away from storm drain inlets and waterways to prevent any potential runoff from reaching these areas.


A common chemical that's often utilized on construction sites is fertilizer - but it's important to store this material properly to avoid any potential runoff issues. Fertilizer bags should be stored in a dry, covered area that's well away from storm drains or other water sources. Additionally, be sure to check with local regulations for any specific requirements regarding the storage and handling of fertilizers in your area.

There are also a number of practices that must be maintained anytime you're applying fertilizer. These include not applying fertilizer directly before heavy rain, avoiding application to frozen ground, and not applying fertilizer within 25 feet of any ditches or waterways.

Chemicals and Fuels

It's critical to store all chemicals and fuels properly when working on a construction site with SWPPP requirements. These items should be stored in sealed containers in a designated area that is well away from storm drains or other water sources. Additionally, be sure to properly label all containers and keep an inventory of chemicals and fuels on site for easy tracking.

There may be further, more specific storage requirements for certain distinct chemicals or fuels, so be sure to check regulations and manufacturer guidelines for any products you're using on the jobsite. Following these storage practices will help ensure safety and compliance throughout your SWPPP program.

Landscaping Materials

Because the landscape itself is often such an important part of the SWPPP and BMP containment setup for any jobsite, it's important to take proper care of any landscaping materials utilized. Bales of hay or other materials used for erosion control should be stored in a well-drained, covered area to prevent any contamination issues. Additionally, mulch and other ground cover materials should be stored away from storm drain inlets and waterways.

At Silver Leaf SWPPP, we can provide further guidance on proper storage techniques for all materials commonly used on construction sites.
