Affordable BMPs That Make a Real Difference
Not every stormwater solution requires a massive investment or complex system. In fact, some of the most effective stormwater Best Management Practices (BMPs) are also simple, affordable, and easy to implement.
Whether you operate a metal recycler, manufacturer, distribution center, or trucking yard, the right combination of small, strategic BMPs can dramatically reduce pollutants — and help you stay compliant under the Industrial General Permit (IGP).


1. Drain Guards and Inlet Protection
Storm drains are the last line of defense before pollutants enter the stormwater system. Installing drain guards, filter inserts, or inlet protection can capture debris, sediment, and hydrocarbons before they leave your site.
Why it works:
Catches trash, debris, and fine particles that collect around yard drains.
Reduces Total Suspended Solids (TSS) and oil & grease exceedances.
Quick to install and easy to maintain between storms.
Pro tip: Frog Environmental’s StormPROOF® Filter Socks and Inlet Filters provide an efficient way to retrofit existing drains. Replace filters regularly to maintain flow and effectiveness.
2. Covered Storage and Sheltering of Materials
Exposed materials are a major source of pollutants during rain events. The most effective low-cost BMP is keeping materials dry and protected.
Affordable options include:
Heavy-duty tarps over outdoor materials or containers
Portable canopies or pop-up shelters for equipment
Permanent awnings or sheds over high-risk areas
Why it works:
Prevents contaminants like metals, oils, and sediment from mixing with runoff
Reduces benchmark exceedances without complex systems
Simple and low-cost to implement across multiple areas
Pro tip: Inspect coverings regularly for wear, tears, or water pooling, and combine with good housekeeping practices to maximize protection.


3. Filter Socks
Filter socks are a versatile, affordable BMP that can be used around drains, along flow paths, or at outfalls. These fabric tubes are filled with specialized filter media that trap sediments, oil, and even dissolved metals.
Why it works:
Targets pollutants like TSS, oil, grease, and dissolved metals.
Flexible placement: they can be installed almost anywhere runoff flows.
Cost-effective and reusable for multiple storm seasons.
Frog Environmental’s MediaPROOF™ line includes filter socks and cartridges using advanced media blends like MetalPROOF™ (for metals) and CarbonPROOF™ (for hydrocarbons and organics).
Pro tip: Replace media after heavy storms or when visibly loaded with sediment for consistent performance.
4. Covers for Drains and Open Containers
Beyond storage areas, directly covering drains and open containers is an inexpensive way to prevent pollutants from entering stormwater during runoff events.
Options include:
Removable drain covers or grate inserts
Tight-fitting lids on buckets, bins, and waste containers
Custom-fitted covers for outdoor equipment or process areas
Why it works:
Reduces debris and contaminants entering the stormwater system
Simple, cost-effective, and easy to maintain
Supports compliance under the IGP and prevents benchmark exceedances
Pro tip: Combine this practice with routine inspections and cleaning of covered areas to ensure maximum effectiveness.


5. Good Housekeeping and Regular Maintenance
Sometimes the best BMP is simply good housekeeping. Routine cleaning and inspection are the foundation of every effective stormwater management program.
Housekeeping BMPs include:
Regular sweeping of paved areas to remove dust, debris, and tire residue.
Prompt cleanup of spills or leaks.
Keeping dumpsters closed and waste storage areas tidy.
Preventing overflows and overfilled containers.
Why it works:
Pollutants on the ground are pollutants in your runoff. A consistent housekeeping schedule dramatically reduces potential exceedances and keeps your facility inspection-ready all year long.
Bonus Tip: Layer BMPs for Maximum Impact
The most successful industrial sites combine BMPs strategically:
Use filter socks around drains already protected by inlet covers
Keep materials and containers covered while practicing regular housekeeping
Inspect and replace media or covers before each storm season
Layering BMPs multiplies their effectiveness, reducing pollutant loads before water even leaves your site.


When Low-Cost BMPs Aren’t Enough
While low-cost BMPs like filter socks, covers, and good housekeeping are highly effective for many sites, they aren’t a cure-all. If your facility experiences major benchmark exceedances or recurring pollutants, these measures often act as a temporary “band-aid” rather than a permanent solution.
In these situations, investing in a stormwater treatment system is usually the most reliable way to reduce pollutant levels and ensure long-term compliance. Systems like Frog Environmental’s StormPROOF® Treatment Systems are designed to handle challenging pollutants including, metals, oil & grease, and sediment, providing a scalable, engineered solution tailored to your site.
Why it’s worth the investment:
Treatment systems may not feel “low-cost” upfront, but they save money in the long run by preventing fines, violations, and potential third-party legal actions
Consistent, engineered treatment reduces the risk of repeated exceedances and costly corrective actions
They allow you to maintain compliance year-round without relying solely on temporary measures
Pro tip: Use low-cost BMPs as your first line of defense, but if exceedances persist, a treatment system is a smart long-term investment that protects both your facility and your budget.
