Public Restrictions after Biosolids Application Services in Washington

biosolids application services washingtonAre you prepping for biosolids application services on a parcel of property you own in Washington? While using biosolids for farming is a safe and eco-friendly solution to conventional chemical-based fertilizers, there are regulations to follow. Failure to follow state guidelines can lead to hefty fines and land audits. An important aspect is that you must restrict public access to the area once biosolids have been applied. The rules can vary depending on the situation, so here are the factors to consider.

Posting Is Required

Upon biosolids application, ensure a written notice is properly posted for the duration that access to the site is cordoned off. There needs to be a notice posted on all access points. In addition, there must be at least one notice posted for every half mile of the perimeter. 

Length of Time

The amount of time public access is to be restricted is based on the potential for public exposure. If the risk is deemed high, restrictions must be enforced for one year. When the probability of public exposure is low, you must restrict the site for 30 days.


Regulatory expectations pertaining to public access restrictions can also be approved by the Washington State Dept. of Ecology. In some instances, a simple “No Trespassing” sign may be allowed, but only if the Washington State Dept. of Ecology gives the nod of approval.

Crop Harvest Waiting Periods after Biosolids Application in Washington

biosolids application washingtonBiosolids application for agricultural use can be highly advantageous in Washington. This is a safer, eco-friendlier alternative to conventional chemical-based fertilizers. However, there are stringent harvesting restrictions that must be carefully followed once the biosolids have been applied. Be sure you follow these regulations to avoid violations.

Above-Ground Food Crops with No Contact

Crops grown above ground that don’t have direct contact with the biosolids can be harvested rather quickly after biosolid land application. These include common crops in the Pacific Northwest like cherries and wheat. The waiting period is just 30 days.

Above-Ground Food Crops with Contact

The harvesting period is usually longer for above-ground crops that have direct contact with biosolids. Examples include lettuce and cucumbers. These require a 14-month waiting period from the date of the biosolid application.

Root Food Crops

Common root food crops include potatoes and onions. These root vegetables often have direct contact with biosolids, resulting in a more extended waiting period. The period varies depending on how long the biosolids stay on the soil. If it’s less than four months, then the waiting period is 20 months. If more than four months, then it’s 38 months.

Feed and Fiber Crops

Feed and fiber crops, such as range land, pasture, trees and cotton, have shorter harvesting times. You can harvest these after just 30 days. However, for fiber crops like turf, waiting times can be as long as 12 months.

Requirements for Biosolids Applied to Agricultural Land Sites in Washington

Requirements for Biosolids washingtonThe use of biosolids for agricultural use is permitted in Washington. This is actually a trending option as it’s a more environmentally friendly solution. Biosolids can improve soil health and not contaminate the groundwater. There are, however, requirements that must be in place before farmlands can apply biosolids. Learn the basic requirements for biosolids and verify that the company you hire goes through the proper channels and follows state/federal requirements.

Remove Manufactured Inerts

Before land application implementation, the biosolids must meet requirements for the removal of manufactured inerts. At a minimum, the material has to contain <1% by volume of approved inerts. In addition, the material must be screened via a bar screen with a maximum of 3/8 inch aperture. Other environmentally-approved materials of similar substances are acceptable.

Test the Soil 

Sites must undergo testing for pollutants before they can be eligible for biosolid land application. The material can’t surpass the ceiling concentration limit. Nutrient levels must also undergo a thorough examination. 

Determine the Agronomic Rate

You have to apply biosolids at the right agronomical rate. The rate is determined by nutrient concentrations in the soil. The company that supplies the materials is responsible for determining this rate. Verify that the company is able to provide this information when making arrangements for biosolids transportation. 

Restrict Public Access

Access to the location where biosolids are applied must be restricted to the general public. At a minimum, the sites must display off-limit signs for as long as the area is restricted.

Why Using Biosolids as Fertilizer is so Good for Crops in Washington

biosolids as fertilizerFarmers and ranchers in Washington understand the importance of using resources that promote the optimal growth of their crops. The more you invest in your crops now the better for future production. One such practice farmers are adopting is the use of biosolids as fertilizer. This is an environmentally friendly solution and a viable alternative to conventional chemical-based fertilizers. Here are some of the benefits of biosolids as a source of fertilizer.

Improved Output

Without the right care, you could see a major decrease in production as soil gradually loses its natural organic matter. Biosolids, though, can enhance crop yield. This is due to the high concentrations of nitrogen, phosphorus, and other essential elements. 

Soil Replenishment

Global demands for produce can put a significant strain on soil availability. Biosolids have the ability to restore organic matter. This is good for aeration and moisture retention. It’s for this reason that biosolids land application has become the main practice for regenerating long-abandoned mine sites. 

Zero Groundwater Pollution

Typical chemical fertilizers can be hazardous to you, your customers, and the environment. Biosolids, by contrast, release nitrogen gradually over the growing season. This makes over-fertilization a non-issue.

How Are Biosolids Generated and Processed?

The biosolid treatment process begins before the wastewater even gets to the sewage facility. Pre-treatment includes filtering all harmful contaminants. The facility removes solid waste, after which the sewage undergoes a number of biological and chemical processes to purify the water. Upon sanitization, the resulting biosolids are transported to farmlands and other locations for distribution.
