Misplaced Priorities at the Virginia Department of Health

The final version of the Emergency Regulations for Alternative Onsite Sewage Systems (AOSS) is posted at the Department of Health web site and can be downloaded for your perusal.

Still contained in the final version is the requirement that single family alternative onsite sewage systems be sampled every five years. This gives the appearance of the emergency regulations that serve to ensure enrichment of the septic service companies and department of health data gathering project. The regulations require two year contacts and basically tie the homeowner to an extremely limited pool of service providers. My own service provider just informed me that his contact rates have gone up almost 25% to meet the requirements of the new regulations and does not include sampling. The requirement for testing is a waste of the homeowner’s money and the inflexibility of the regulations will not serve to better protect public health and the environment. To work regulations must be effective, clear and not overly burdensome.

The proposed requirement for sampling and analysis by single family homeowners at a single point in time is misleading and it has no scientific value beyond data gathering. Results from a single test would normally vary in a range around the design parameters and so are statistically misleading and not representative of sound sampling methods. The Department of Health is using this requirement to data gather on the homeowner’s nickel. There are no standards for the sample results.

Perhaps I am wrong and the Department of Health intends to use the design parameters of the system as sampling standards. Let’s walk through this. If the system “failed” to meet the design parameters the next steps would be to make adjustments to the use or operation of the system. Then, to verify that these changes had the desired result, the system would be retested, again at the home owners expense to verify effluent within the design parameters. How many rounds of testing would be required to determine that the “average” parameter was met? Or would the Department of Health simply ignore the results and allow the systems to continue to operate until the next five year sample date? In real life there will be variability in performance. At what cut off does the VDH take enforcement action, or require further investigation? Without these answers a sampling program can be no more than data gathering.

All of the approved AOSS systems were demonstrated to perform satisfactorily to meet the requirements of the Commonwealth. Operation and maintenance of these AOSS systems by professional operators (or trained homeowners) ensures that a single family home (low volume) unit is functioning properly. These are not very complicated systems, they contain tanks, pumps and filters and natural process of bacteria breaking down the waste. As an experienced chemical engineer I know that a single sample once every five years would be misleading. Testing of a septic system operation at a single point in time can be impacted by volume, load, temperature and humidity and is not representative of overall performance. These systems do not have controlled sample ports and the field workers servicing single family homes have no sampling training and under the regulations are not required to have any form of license. Temperature and pressure will not be recorded, temperature will not be controlled during hold and delivery, and sampling will be unprofessional. There are no standards for appropriate sampling of a septic system. Nonetheless, I will be charged hundreds of dollars. In addition, the results of the single sampling event can be easily manipulated by adding a large quantity of clean water from the garden hose to the location being sampled. In my case, simply adding water to the third tank will ensure that the data obtained is entirely worthless. Such a single sample test would never have been adequate by itself to get an AOSS approved for use.

What is even more annoying than paying for the data gathering efforts of the Department of Health is their failure to put their first priority on the primary duty of protecting public health and the environment. If they wanted to do something useful they could test private drinking water wells annually. This data would ensure the public health and could identify failing or failed AOSS and traditional septic systems that had impacted groundwater. However, the massive costs of this would be visible and the pain of the cost felt by the public. At least, the groundwater of the Commonwealth could be carefully tracked. The Virginia Department of Health does not require homeowners to test their drinking water wells annually or even every five years. There is no logic behind the requirement that I should be spending hundreds of dollars to have some septic operation company sample and then send for analysis a sample from my third septic tank, but does not require me to ever pull a sample from the faucet of my house. Evidently, the Department of Health regulatory process was very influenced by the input from the industry.

Alternative Septic Regulation and the Virginia Single Family Homeowner

Here are some additional thoughts on the proposed Alternative Onsite Sewage System (AOSS) Regulations as they pertain to single family homeowners. These regulations were published September 28, 2009 by the Virginia Department of Health and the comment period is open until October 28, 2009.

The proposed regulations implement the 2007 legislation and require professional operators certified by DPOR to operate and maintain all alternative onsite septic systems, AOSS, including those of single family homes. The Virginia code requires the owner of an AOSS, to have that system operated by a licensed operator, as defined in § 32.1-163, and visited by the operator as specified in the operation permit. Effective July 1, 2009, Virginia law requires that soil evaluators, installers, and operators of onsite sewage systems must be licensed by the Board for Waterworks and Wastewater Works Operators and Onsite Sewage System Professionals at the Department of Professional and Occupational Regulation (DPOR). For the interim regulations nothing can be done to change that. However, the proposed regulations go on and require the same operation, maintenance, sampling, record keeping behavior in single family home owners as required of clustered systems of up to 39.999 gallons per day. This serves to add to the profitability of the licensed operators and the expenses for the homeowner without benefiting public health or the environment.

The proposed testing requirement is not authorized or required by statute and is useless. Laboratory testing of a septic system at a single point in time can be misleading. Operating performance is impacted by volume, load, temperature and humidity, and a single sample is not representative of overall performance. These approved AOSS have already been tested to demonstrate an acceptable operating average performance over a period of time and range of conditions. The authorizing statute requires regulation of the operation and maintenance of AOSS but does not authorize or require testing or reporting unrelated to this purpose. An AOSS that is operated and maintained by a professional operator meets the requirements in the law and protects the environment. Regular inspections and maintenance should serve to identify systems that are not functioning properly.

The requirement for operation and maintenance by a licensed operator favors operator over homeowners, and does not require certification by the manufacturer of all approved systems for implementing operation and maintenance programs. Effectively, licensed operators unqualified to maintain a particular system can contract with homeowners to operate and maintain the system. This bias is compounded by the record keeping, and evidence of maintenance contract requirements making it extremely difficult to change operators. The DPOR and VDH do not give homeowners any tools to evaluate operators, yet tie the homeowner to the operator by the requirement to “Maintain a relationship with an operator.” Before a contract expires the homeowner is required to have another one in place.

Finally, a home owner is required to keep a copy of the Operation and Maintenance Manual (O&M Manual) on the property where the AOSS is located, make the manual available to the Department upon request and make a reasonable effort to transfer the O&M Manual to any future owners. The requirements for the manual are listed in the proposed regulations, and appear to be another profit center for the licensed operators to provide these manuals to homeowners. Since the homeowner is not allowed to operate or maintain their systems themselves a manual is a useless pile of paper conveying little information to untrained reader. A simple diagram of the system, physical location of the components and a list of components, their manufacturer and their function would suffice for single family systems. This short information brochure would more likely to be read and understood by the homeowner and could serve as an educational tool and be useful in shopping for a licensed operator.

The success of the regulations in protecting the environment and public health will depend on the compliance of the AOSS owners. For the individual homeowner the regulations should be clear, fair and easily understood by a layman reading them. Compliance with the regulations will suffer if they are, or are perceived, to be excessively costly or burdensome and without benefit to public health and the environmental. Though I believe there should be a method for a homeowner to become licensed to operate their own systems, these approved AOSS need to be annually inspected and properly maintained by professional or trained operators. A monthly cost for a maintenance contract of around $40 will be perceived as an additional cost like a property tax, but is manageable. The other portions of these regulations make the cost to the homeowner too high without providing additional protection to public health and the environment.

Commonwealth of Virginia Proposed Septic System Regulations

On September 28, 2009 the Virginia Department of Health published their proposed Alternative Onsite Septic System, AOSS, regulations for public comment. The window for public comments closes on October 28, 2009. The comment period is closed.


The proposed regulations implement the legislative mandate of 2007 and require professionals operators certified by DPOR to operate and maintain all alternative onsite septic systems, AOSS. The Virginia code requires the owner of an AOSS, to have that system operated by a licensed operator, as defined in § 32.1-163, and visited by the operator as specified in the operation permit. Effective July 1, 2009, Virginia law requires that soil evaluators, installers, and operators of onsite sewage systems must be licensed by the Board for Waterworks and Wastewater Works Operators and Onsite Sewage System Professionals at the Department of Professional and Occupational Regulation (DPOR). Prior to July 1, 2009, Virginia law did not require a license to practice as an onsite sewage system operator. DPOR’s regulations for licensing operators does not have any sort of exemption or modified certification for homeowners, but should. It is irrational that home owners can operate direct discharge septic units, but the legislation requires that all single family AOSS units be operated and maintained by a licensed operator.

In their proposed regulations the Virginia Department of Health did not have the option of allowing homeowners to operate and maintain their own systems without modifying the DPOR licensing requirements. The legislation passed in 2007 required that licensed operators perform these tasks. The Department of Health, fully aware of the problem, did not attempt to develop an alternative certification for homeowners, instead they choose to propose that single family home AOSS (under 1,000 gallons per day) be required to be operated by a licensed operator, maintained by a licensed operator and sampled. These are the same requirements that are used for AOSS units processing up to 39,999 gallons per day. These requirements combined are far in excess of what is required to ensure that these systems function as designed. It is to be noted that most single family homes operate at far fewer than 1,000 gallons a day.

The requirement for operation and maintenance by a licensed operator favors operator over homeowners, and does not require certification by the manufacturer of all approved systems for implementing operation and maintenance programs. This bias is compounded by the record keeping, and evidence of maintenance contract requirements making it extremely difficult to change operators. I am not give any tools to evaluate operators, yet sa a homeowner I am tied to the operator by the requirement to “Maintain a relationship with an operator.” Before a contract expires the homeowner is required to have another one in place. Finally, a home owner is required to keep a copy of the Operation and Maintenance Manual (O&M Manual) on the property where the AOSS is located, make the manual available to the Department upon request and make a reasonable effort to transfer the O&M Manual to any future owners. The requirements for the manual are listed in the proposed regulations, and appear to be another profit center for the licensed operators to provide these manuals to homeowners. A simple diagram of the system and a list of components and their function would suffice for single family systems. The question is why the VDH is proposing such punishing regulations for single family AOSS that go beyond the need to properly maintain these systems, but serves as a profitability act for the licensed operators.

Alternative onsite septic systems are designed to be state of the art, meeting EPA's treatment standard one. This exceeds the standards for sewage treatment plants and replenishes existing groundwater systems. These alternative onsite systems can be more sustainable to the surrounding ecosystem than sewers and centralized waste treatment and are certainly less expensive for the homeowners in sparsely populated areas. However, the systems need to work properly and these newer alternative systems with multiple tanks, compressors and various parts require consistent maintenance to continue working properly. Rather than attempt to educate the homeowner and offer cost effective solutions to ensuring that AOSS are maintained properly, the VDH has proposed three layers of oversight within the regulations that are likely to result in avoidance of compliance and potentially abandonment of the technology. The VDH is treating low volume single family home AOSS the same way as clustered systems. Is this the best answer for Virginia?
