Common Biosolid Uses in Washington

biosolid uses washingtonBiosolids have immense value in agricultural applications.  It helps to have a baseline understanding of biosolid uses and the scenarios in which they can be applied to your land. Once you have this understanding, you can determine whether this is a good practice for your property. Learn how this nutrient-dense fertilizer can be applied and how it can help your business both environmentally and economically.


Agriculture is the most typical use-case scenario for biosolids. This is due to the rich composition of minerals like nitrogen and potassium. If applied in the right concentrations, this can contribute to healthy growth and production without resorting to chemical-based fertilizers. Most conventional fertilizers contain unnatural preservatives that may cause long-term harm to your crops.

Forestry Application 

Biosolids can assist the growth of forest timber. This enables better regrowth, especially during harvest season. This can be of tremendous value during times of timber and wood scarcity. It also assists in reforestation efforts in areas affected by wildfires. Biosolid is now in wide use in wooded areas in the Pacific Northwest.

Home Lawns and Gardens

Biosolid fertilizers have applications that are beyond agriculture and reforestation. They are also great for residential lawns. A landscaper can perform a soil test on your property and determine specific nutrient deficiencies. Biosolids may increase soil health for your lawn, yard, or garden.

Advantages of Applying Biosolid Nutrient Content in Washington

Biosolid nutrient content WashingtonAre you contemplating biosolid land application services and are curious about the advantages? Biosolid nutrient content is high in nutritional content that can be good for soil and croplands. The more you understand the nature of biosolids the better you can prep your land for the application process.


Biosolids are a good source of nitrogen, which is an essential element for healthy crop production. Nitrogen creates chlorophyll, which is vital for hearty vegetable and fruit growth. An abundance of nitrogen in the soil increases the odds of a good harvest.


Phosphorus induces energy transformation in plants and plays an enormous role in photosynthesis. It’s also vital in shuttling sugars and other nutrients to crop roots. Finally, biosolids contain phosphorous, which further aids in growth.


Potassium is a nutrient that assists in shuttling water into plants and producing enzymes. It also helps open the plant’s stomata, in turn increasing its water and oxygen intake. If crops are deficient in potassium, it can stunt growth. Biosolids prevent deficiency in this useful mineral.


Calcium provides support for plants to retain a healthy structure. It’s similar to the way calcium helps people maintain strong bones and ligaments. It also fortifies tissue and cell wall growth. Crops with ample calcium are less likely to face physical and chemical stress.

Can Your Farm Benefit from Biosolid Nutrient Content in Washington?

If you wish to reap the benefits of biosolid nutrient content in Washington, then contact Tenelco to learn more. In addition to biosolids application, we also perform septage receiving. Whatever the case, let us help your crops produce optimal yields and consistent growth.

Common Questions Related to Septage Receiving Services in Washington

septage receiving services washingtonMany residences and local business owners have inquiries about septage receiving services in Washington. Perhaps you’re a contractor or are managing the system on your own. Regardless, the disposal process can be cumbersome and complex with dozens of regulations to follow. Fortunately, there are professional services that can perform the septage receiving and disposal on your behalf, thus completely removing this job from your hands. Before you consider the service, there may be some questions on your mind. Here are the common inquiries we receive from customers.

Is a Permit Required?

Washington takes septage services very seriously and has passed varying legislations that ensure disposal is done in a way that doesn’t negatively impact the environment and wildlife. Septage disposal requires a permit, and any disposal done without the required paperwork can result in serious legal ramifications.

Can I Transport Septage Myself?

Transporting waste isn’t a simple DIY process that can be carried out with a sturdy barrel and a pickup truck. On the contrary, it requires highly sophisticated commercial equipment. Instead of purchasing the cost-prohibitive equipment, it’s recommended to just hire a professional with the existing equipment.

What Is Biosolids Application?

In a similar vein, individuals and companies performing biosolids transportation and application must follow regulations in accordance with Washington state. In this process, the waste isn’t dumped in a landfill. Rather, it’s converted into biosolids that can be applied to croplands for agricultural purposes.  This is an eco-friendly alternative to traditional fertilizers, which are often heavily processed.

Biosolids Application Terms to Know in Washington

Biosolids Application Terms washingtonAre you considering biosolids application for your agricultural site? If so, there are biosolids application terms you should familiarize yourself with. Learning some of the basic jargon will help you understand how the process works and why it’s beneficial.

Aerobic Digestion

Aerobic digestion is the process by which organic materials in the biosolids undergo biochemical decomposition. What results is a mix of water and carbon dioxide. Aerobic digestion should not be confused with composting. While the two are similar, aerobic digestion has a slightly different decomposition process where carbon dioxide and methane gas are produced.

Agricultural Land

Agricultural land in this sense refers to any parcel of land eligible for biosolids application. This includes any land where crops are grown, especially farms and ranches.

Agronomic Rate

The agronomic rate is the level of biosolids to be applied so the soil receives the optimal nitrogen amount for best results. The range also needs to be within limits so as not to contaminate nearby groundwater.

Ceiling Concentration

Ceiling concentration is the maximum level of pollutants permitted in a biosolids sample. When pollutant levels surpass the ceiling concentration, the material is deemed sewage sludge, which is considered hazardous and unsuitable for application.


Composting is intended to induce aerobic decomposition, which can be beneficial for vegetation growth. The term refers to the biological degradation of organic matter, but under a controlled setting. 


EPA is an acronym for the United States Environmental Protection Agency. This agency creates guidelines regarding biosolids transportation and application.

Site Management Restrictions after Biosolids Application in Washington

Site Management Restrictions after biosolids application washingtonBiosolids have multiple agricultural uses, typically functioning as a sustainable, eco-friendly alternative to conventional chemical fertilizers in Washington. If you’re contemplating using biosolids, you should familiarize yourself with the rules regarding site management restrictions for biosolids upon application. Failure to adhere to the following guidelines could result in heavy fines.

Surface Waters

Biosolids application is prohibited within 100 feet of surface waters. It’s possible, though, to have a closer buffer zone approved by Ecology. In addition, Ecology may mandate alternative application guidelines on a case-by-case basis.


Likewise, biosolids application must be 100 feet away from wells. If there’s a well on the property, you’ll have to take the required precautions to be certain the well water isn’t contaminated during or after the application procedure. Keep in mind Ecology is the only governing entity that can approve a different buffer zone.


No Class B quality biosolids applications are permitted in wetland locations. In some scenarios, however, you may be able to acquire consent from Ecology under the right circumstances.

Flooded, Frozen, or Snow-Covered Areas

You cannot apply biosolids on soil that’s flooded, frozen, or covered by snow. Consequently, this may delay services as the application will likely only be granted once the temperature warms up. As with the other situations, there may be a workaround if you can get approval from Ecology.

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.

Interested in Using Biosolids as Fertilizer in Washington?

Do you own farmland in Washington? If so, using biosolids as fertilizer is a good practice to adopt that just might improve your bottom line. It also has the greater benefit of preserving the environment. If this is a change you want to adopt, contact Tenelco to discuss plans for your agricultural development. We perform biosolid transport as well as septage receiving. In addition, we have all the needed permits to ensure our clients are within regulation.
