Performance Goals and Treatment Categories Explained

Understanding performance goals is essential for anyone working with tape treatment in stormwater management. These benchmarks ensure that each system delivers reliable pollutant removal and meets regulatory expectations. By categorizing treatment standards, professionals can select the right approach for site-specific needs and compliance.

Pretreatment and Basic Treatment Standards

Pretreatment is the first line of defense in tape treatment, targeting larger particles and debris before water moves into more advanced processes. The primary goal here is to achieve at least 50% total suspended solids (TSS) removal when influent concentrations fall between 100 and 200 mg/L. If the influent is below 100 mg/L, the effluent should not exceed 50 mg/L.

Basic treatment takes this a step further. Systems must remove 80% of TSS for influent in the 100–200 mg/L range, and reach an effluent goal of 20 mg/L or less for concentrations under 100 mg/L. These standards protect infiltration sites and downstream facilities from excessive sediment loads.

Applying these tape treatment standards helps ensure consistent performance, especially during high-flow storm events.

Oil and Metals Treatment Criteria

Tape treatment systems designed for oil removal must ensure that no visible sheen is present in effluent, with a daily average total petroleum hydrocarbons (TPH) of 10 mg/L or less, and a maximum of 15 mg/L for any grab sample. This prevents harmful oils from entering local waterways.

Metals treatment builds on basic standards. Devices must achieve at least 30% removal of dissolved copper (for influent between 0.005 and 0.02 mg/L) and 60% for dissolved zinc (0.02–0.30 mg/L). If concentrations exceed these ranges, all valid data must still be included in performance calculations.

To illustrate, consider a device handling runoff after a major rain event. Accurate data collection ensures that tape treatment results reflect real-world efficiency. For more on where the industry is heading, see the 2025 Association Forecasts.

Phosphorus and Construction Treatment Requirements

Phosphorus management is a key component of tape treatment, especially in areas sensitive to nutrient pollution. Systems must remove at least 50% of total phosphorus for influent concentrations between 0.1 and 0.5 mg/L, in addition to meeting basic treatment standards for TSS.

Construction site runoff poses unique challenges. The effluent must not exceed 5 NTUs above background turbidity, or increase turbidity by more than 10% if background levels are over 50 NTUs. Oil sheen and pH must also be carefully monitored. These requirements protect receiving waters from spikes in sediment, nutrients, and contaminants during active development.

A real-world case involved a major infrastructure project where tape treatment devices were deployed to maintain compliance during heavy rainfall. The system’s ability to meet phosphorus and turbidity standards was crucial for project approval and environmental protection.

Data Integrity and Avoiding “Cherry Picking”

Maintaining data integrity is fundamental in tape treatment certification. All valid samples above concentration ranges must be included in performance calculations. Selectively excluding results, known as “cherry picking,” is strictly prohibited.

This approach ensures scientific integrity and regulatory trust. If a vendor omits data to improve reported results, certification can be revoked and future applications scrutinized. Tape treatment relies on honest reporting to advance technology and protect public health.

To support this, rigorous quality assurance and transparent data sharing are essential. By upholding these principles, the tape treatment field continues to evolve with confidence and credibility.
