The changes, under the Wisconsin Department of Natural Resources' ch. NR 151, Wis. Adm. Code, relate to Silurian bedrock, which are areas where the soil depth to bedrock is shallow and the bedrock may be fractured.
"The main purpose of this targeted performance standards is to reduce the risk for contamination in groundwater from manure applications on shallow bedrock soils," said Mary Anne Lowndes, DNR Watershed Management Section chief.
Lowndes said Silurian bedrock soils identified in the rule revisions are dolomite bedrock with a depth of 20 feet or less. The rule targets an area in the state that may include portions of Brown, Calumet, Dodge, Door, Fond du Lac, Kenosha, Kewaunee, Manitowoc, Milwaukee, Ozaukee, Racine, Sheboygan, Walworth, Washington, and Waukesha counties.
"Within a specified area, the rule sets forth manure spreading rates and practices that vary according to the soil depth and texture," said Lowndes. "For Silurian bedrock, the most restrictive practices apply to those limited areas with the highest risk for pathogen delivery, zero to five feet in depth, and less restrictive requirements apply in areas with five to 20 feet to bedrock."
Lowndes added that Concentrated Animal Feeding Operations (CAFOs) in the Silurian bedrock areas will be required to comply with the standards in the new rule, when it is incorporated into their permit under the Wisconsin Pollution Discharge Elimination System (WPDES), and a cross reference to the targeted performance standard language has also been added to ch. NR 243, Wis. Adm. Code., which applies to CAFOs subject to WPDES permitting. Non-permitted farms in Silurian bedrock areas will also be required to comply with the standards in the rule.
Lowndes added the DNR has worked with the University of Wisconsin Department of Soil Science to offer a Silurian bedrock map (exit DNR) tool that can be used to identify areas where the bedrock soil depth is less than 20 feet, and that the department is working with the Department of Agriculture, Trade, and Consumer Protection and county land conservation departments on how best to implement the new rules.
The new rule is based on a long-term effort by the department to seek public input on changes to NR 151, including conducting studies, public meetings and hearings and hosting a technical advisory committee and Groundwater Collaboration Workgroup that met between 2015-2017.
About 190,000 gallons of liquid manure were released from an above-ground storage tank at the dairy operation on April 12, 2017, the Oregon Department of Agriculture said.
The manure pooled in a field near the dairy barns, flowed across three other landowners’ properties, and ended up in a slough that connects to a drainage system that pumps water into the Tillamook River, which then enters the bay. READ MORE
Ask yourself these questions:
- Does every employee understand the risks associated with confined manure handling systems?
- Have they received proper training when dealing with confined manure handling systems?
- Do you have the appropriate hazard signage posted near the confined manure handling system, warning people of the dangers?
- Do you have the appropriate safety gear available and have you provided instruction to employees on using the equipment?
- Do you have employees with limited English speaking skills?
- Do they fully understand the safety risks and signage provided?
- Do employees and family members have the ability to communicate location directions in an emergency 911 call?
So what is the risk with confined manure handling systems? Understanding that there is risk associated with manure pits and manure lagoons is important. They both produce toxic gases as the manure undergoes anaerobic digestive fermentation. The gases produced and the characteristics of each are below:
Methane – is an odorless gas that is flammable or explosive at concentrations of 5 to 15 percent by volume of air. The gas is lighter than air and typically found near the top of the pit and high enough concentrations can cause death by suffocation.
Hydrogen sulfide – is an extremely toxic gas with a “rotten egg” smell at low concentrations and which at high concentrations can paralyze the olfactory senses. It is heavier than air and often settles towards the bottom of the manure pit. At low concentrations it can cause dizziness, headache, nausea, and respiratory tract irritation. At high concentrations it can cause unconsciousness, respiratory failure and death within minutes. It is also explosive at various concentrations.
Carbon Dioxide (CO2) – is an odorless gas that is heavier than air and often settles near the bottom of the manure pit. At low concentrations it causes labored breathing, drowsiness and headaches. In high concentrations it can displace enough oxygen and cause death via suffocation.
Ammonia (NH3) - has sharp odor characteristics that irritate the eyes, nose, throat and lungs. Exposure to high concentrations can be fatal.
Besides understanding the various types of gases produced in confined manure handling systems, you should also follow these guidelines when working around confined manure handling systems.
These are enclosed manure storage structures, which should be equipped with ventilation systems. They are often found in dairies as manure is pumped out to a lagoon or in confined swine operation buildings or certain types of beef finishing operations that utilize a confined building.
Follow these safety guidelines around manure pits:
- Keep all manure pits ventilated and fans working properly.
- Keep all manure pits covered with appropriately ventilated grating.
- Post hazard signs near all manure pit entry point locations.
- Never enter a manure pit unless absolutely necessary and only when proper safeguards are utilized.
- If entry into the pit is necessary, test the air for toxic gases.
- Never enter a manure pit unless someone is standing by and maintaining constant contact. The person standing watch should be able to lift an unconscious person wearing a safety harness attached to a lifeline. They should NEVER enter the pit trying to rescue someone and have the ability to communicate necessary information in case of an emergency 911 call.
- Always wear a safety harness that attached to a mechanical device such as a winch, hoist or pulley. This is your lifeline, so the person on the outside must maintain constant contact with the lifeline.
- Always wear a positive-pressure, self-contained breathing apparatus (SCBA).
- Provide a powered, explosion proof air ventilation system for each manure pit that will help bring in a continuous fresh air supply.
- NEVER enter a manure pit to attempt a rescue without a safety harness and proper respiratory protection!
They also produce toxic gases in localized layers, which, especially on hot, humid days with little breeze can cause a health hazard and potential death. Gases are readily released when lagoons are agitated to remove manure to be incorporated as fertilizer into the fields. They often have a thick liquid, floating crust, which can make swimming and buoyancy difficult if you were to slip or fall into the lagoon. Additional safety guidelines for manure lagoons are as follows:
- Open-air lagoons should be fenced off around the perimeter with locked access gates to keep unauthorized people or unwanted animals from accidentally entering them.
- Hazard signs posted at entry points warning of toxic gases and drowning dangers.
- Wear a safety harness attached to a lifeline with someone on the other end that can drag you out if it is necessary to enter the lagoon.
- Rescue equipment such as flotation devices and lifelines attached to every manure pump.
- Move slowly around manure lagoons as the ground can be uneven causing a person to trip and fall.
- Never work alone but all other unnecessary bystanders should stay away from access points or pump-out points.
- No horseplay allowed in these areas.
- No smoking or open flames allowed near agitation or pumping areas due to the explosive gases that may be present.
- If equipment breakdown occurs during agitation or pumping shut it down and remove it from the lagoon area before servicing.
- Follow the same 911 emergency call guidelines as manure pits, be able to describe the situation, number of victims, location and directions.
“As you are well aware, hurricanes can produce a lot of rain over a short period of time so now is the time to check your lagoon levels,” she said. “If you expect you are near the path of this hurricane, lower your lagoons to the stop pumping levels, which can be found in your nutrient management plan. If you have any questions, please don’t hesitate to contact me. Just always remember safety comes first so be careful out there.”
She also forwarded an alert from the University of Georgia’s agriculture climatologist, Pam Knox, who has been watching the progress of Hurricane Irma.
“If you are in south Georgia, you could see impacts from the storm as early as Saturday [Sept 9], although most likely you will not see much until Sunday [Sept 10] morning,” Knox said. “The major impacts from the storm in Georgia are likely to be strong winds, locally heavy rains and potential storm surge and high waves if you are along the coast. Some tornadoes are also possible. Because the storm is so powerful, the strong winds and rain could spread out a long way from the center of the storm, so do not let down your guard if the center does not come close to you.”
“With wet soils and trees that have been stressed from droughts in previous years, I expect a lot of trees to fall, cutting electrical power to many locations if the storm does not weaken as it moves up from Florida.”
“Since power may be out, it would be wise to make sure you have gas and cash for several days just as a precaution,” Knox stated. “Because Irma is moving along at a pretty good clip, we do not expect to see the amount of rain that Texas received from Harvey, but local areas could see some fresh-water flooding. Because of that, agricultural producers may wish to move machinery and livestock to higher terrain.”
Knox will be posting updates on her blog [http://blog.extension.uga.edu/climate] as well as on Facebook at SEAgClimate and on Twitter at @SE_AgClimate through the week.
Increasing this awareness led Dan Andersen, assistant professor and ag engineering specialist with Iowa State University Extension, to create a series of four publications that provide information and resources to help farmers stay safe when working with manure.
"One breath of hydrogen sulfide at 500 parts per million is enough to render someone unconscious almost immediately," warns Andersen. "When you are working with a manure pit, and once you realize the gas is a problem, it's usually too late. Hydrogen sulfide gas smells at 1 to 2 parts per million, but levels above that amount knocks out your ability to smell, so our natural detection system goes away."
Pit gas monitors recommended
Information about the importance of monitoring for hydrogen sulfide and the types of monitors available for purchase is available in publication AE 3603, Hydrogen Sulfide Safety — Monitoring.
Monitors are available from ISU Extension, which has several models for farmers to test. READ MORE
Mike Biadasz, 29, went out to agitate a manure pit on his family's farm near Amherst, when the crust layer on top of the pit opened, hydrogen sulfide gas was expelled. He died on Aug. 15, 2016 after being poisoned by methane gas.

About 75 emergency response personnel and farmers gathered June 12 at Cottonwood Dairy Farm just outside Wiota for a training session designed to help them understand the hazards of manure storage and handling systems. The workshop focused primarily on confined space and manure as safety procedures.
Cheryl Skjolaas, UW-Madison/Extension agriculture safety specialist, and Jeff Nelson, UW-Madison machinery specialist and volunteer firefighter, took participants to various spots on the farm to see the farm's manure pits and associated equipment during the training session.
They talked about equipment that is safe to use in confined spaces, such as gas monitors and ventilation equipment, and fall protection devices. READ MORE

As part of research being conducted on behalf of Swine Innovation Porc, scientists with the University of Saskatchewan, the Prairie Swine Centre, the Prairie Agricultural Machinery Institute and VIDO-InterVac are working to automate the cleaning of swine transport vehicles to speed up the process and cut the cost.
VIDO-InterVac is responsible for identifying approaches to inactivate the key pathogens responsible for the transmission of disease.
Dr Volker Gerdts, the associate director of research with VIDO-InterVac, said in this project scientists focused on temperatures and the amount of time at those temperatures needed to inactivate 12 pathogens, six bacteria and six viruses, considered important to the swine industry.
"Viruses in general are a little bit more difficult to inactivate because they are inside the cell but we also had a few bacteria, Streptococcus suis for example, which is also relatively resistant to heat," Dr. Gerdts said.
"If you were able to use a very high temperature, like 80 degrees, all of these pathogens will be destroyed within a very short period of time," he said. "Going lower, like at 60 or 65 degrees Celsius, then it would take much longer so it's really a combination of temperature and time.
"I can't really give you all of those but, if you were to go with a high temperature, like 80 degrees for example, that would be sufficient to kill most pathogens within minutes," he added. "If you were going to go with 70 or 65 degrees then you're probably looking more at 15 minutes or something like that."
Dr Gerdts noted the industry is using this approach already.
He said after cleaning, washing and disinfecting, they're baking the trailers but the various units are using slightly different temperatures and slightly different schedules.
Luzerne County Court of Common Pleas Judge Thomas F. Burke Jr. decided to grant motions for summary judgment for the defendants and against a long list of plaintiffs who are landowners and neighbors of the hog operation. READ MORE
While the conditions are still fresh, every operation should take stock of manure storage options and look for ways to avoid application in these situations. Over the last few weeks, I have heard more comments than usual from farm and non-farm folks alike about seeing neighbors spreading manure on barely trafficable fields or even from the edge of the road.
If you find your operation in this situation, or if you strained to find fields that can hold up the tractor and spreader without getting stuck, runoff risk is likely to be high and application should be avoided whether you are a regulated farm or not. Spreading just before rain or snowmelt can be just as risky, even if a field can be driven on without getting stuck.
For stackable manure in the short term, temporary pile locations can be identified with the help of SWCD, NRCS, or private sector planners until better storage options can be installed.
New York State and federal cost share options are available annually; meet with your local SWCD and/or NRCS staff to start the process. The Dairy Acceleration Program can help with cost of engineering on farms under 700 cows.
Position your operation for the future: evaluate manure storage needs and implement solutions.
April 11, 2017, Charles City, IA — A revised resolution aimed at protecting the health of workers at large animal confinement operations was discussed by the Floyd County Board of Supervisors recently, and its sponsor hopes changes will result in more support this time.

April 10, 2017, Windsor Heights, IA – Plans to enable farmers and consultants to submit manure management plan updates electronically will lead off the April 18 meeting of the Environmental Protection Commission.
April 10, 2017, Owatonna, MN – Public perception can dictate and lead to public policy. It is important for agriculture professionals to step out of their own boots and look at how they do business from the perspective of the general public. Is it a positive image? If not, the public may seek regulations to change it.
Rick Martens, the executive director of the Minnesota Custom Applicators Association, spoke to a group of manure applicators that were continuing their Commercial Ag Waste Technician training. READ MORE
