- To educate our customers regarding how to recognize the odor of natural gas, and how to respond if they detect possible gas odors. Early recognition of a gas odor and proper response can save lives.
- To raise awareness among affected public and key stakeholders in the communities we regarding buried natural gas pipelines. A more informed public will also understand what steps that they can take to prevent third party damage to underground pipelines, and respond properly if they cause damage to our pipelines.
- To help excavators understand the steps that they can take to prevent third party damage and respond properly if they cause damage to our pipelines.
- To educate the public regarding the symptoms of carbon monoxide (CO) poisoning, and the appropriate treatment should CO poisoning be suspected.
- To educate the public about the protection of gas meters from damage by falling objects and other hazards.
- Call before you dig. State law requires that, before digging, you call the national hotline at 811 at least 72 hours before you begin any excavation work.
- Wait the required 72 hours. At no cost to you, technicians will mark the location of utility lines on your property. Once all lines are marked, you can then safely begin your digging project.
- Respect the markings for your safety.
- Dig with care. If you accidentally hit the pipeline, no matter how minor it may seem, call us immediately at 1-864-942-8100 (1-877-662-3360)
Excess Flow Valve Notification for Residential Customers
As required by the U.S. Department of Transportation (DOT), you are hereby notified that an excess flow valve (EFV) which meets the minimum DOT performance standards is available for installation on your natural gas service line.
An EFV is a safety device that is designed to automatically stop the flow of natural gas when (if) the flow of gas through the device exceeds a pre-determined rate due to a rupture or break in the downstream piping. The EFV is normally installed at (near) the service line's connection to the gas distribution main (in many cases, near the street), and protects against the dangers associated with an uncontrolled escape of natural gas.
t should be noted that these devices generally do not protect against slow leaks such as those caused by corrosion, loose fittings, or leaks beyond the gas meter (house piping).
Installation of an EFV
If you would like to have an EFV installed at no cost to you, simply call Greenwood CPW at 864-942-8100 to request the EFV installation. The EFV valve will be installed within 60 days from the day of the request.
Should you have any more questions, please give as a call at 864-942-8100.
Call CPW first to prevent cross bore danger
When you have a sewer or septic line blockage outside the walls of your home, call CPW to meet your plumber on the scene and check for potentially dangerous cross bores.
What to do
To safely clear a blocked sewer or septic line:
- Determine if the blockage is within the walls of your home. Only outdoor blockages pose a risk.
- If you think the blockage is outside, ask your plumber to call CPW at 864-942-8100 or 877-662-3360 at least one hour before attempting to clear it. We'll immediately dispatch a technician, who can usually arrive at your location within 60 minutes.
- Working with your plumber, the technician will locate the sewer and gas lines and make sure it's safe to proceed. This service is free of charge.
Your plumber can help
Your plumber or drain-cleaning professional may recommend inserting a camera in your sewer to look for cross bores. This is a good practice, and if a cross bore is found, CPW will reimburse you for the camera inspection. However, you should always call CPW to work with your plumber to precisely locate both your sewer and gas lines before using a cutting tool, because a cross bore may be concealed behind other obstructions and not be visible to the plumber's camera.
- It is illegal to tamper with or remove CPW's pipeline markers
- Permanent structures such as storage buildings, sheds or swimming pools, or bodies of water may not be built within the right-of-way.
- Trees may not be planted within the right-of-way.
- Changing the ground elevation by either adding or removing soil from the right-of-way is not permitted
Natural gas is a colorless, odorless gas that is lighter than air. It will rise if there is a leak. A product called mercaptan is added to our gas to give it an odor similar to "rotten eggs". This is a safety measure to assist in detecting a gas leak.
Some signs of a gas leak include:
- A gaseous or hydrocarbon odor (due to the mercaptan)
- Blowing or hissing sound
- Dust blowing from a hole in the ground
- Continuous bubbling in wet or flooded areas
- A spot of dead or discolored vegetation in an otherwise green area
If you smell gas:
- If possible, eliminate any source of ignition such as any open flame, cigarettes, matches, lighters, etc.
- Do not smoke. Do not use lighters or matches
- Do not turn off/on any switches or appliances
- Do not use a phone or cell phone
- DO leave the area and go to a safe location
- Then call 864-942-8100 and provide the following emergency Information:
1. Your Name
2. Address or location
3. Telephone number
4. Type of building or site
5. Location of odor (inside by appliance or outside of building)
Greenwood CPW personnel are on call 24 hours a day 7 days a week - 864-942-8100.
- Carbon monoxide (CO) is an odorless, colorless, deadly gas. It can kill you before you know it because you cannot see it or smell it.
- Carbon monoxide can be formed when your appliances are not operating properly.
- Symptoms of CO poisoning include: Flu like symptoms - headaches - drowsiness- nausea - blurred vision .If you think you have CO poisoning, go outside into fresh air. If needed, get medical attention.
In accordance with Federal Department of Transportation Pipeline Safety Regulations Rule 49 CFR 192.16, Greenwood CPW is required to notify you of the requirements concerning the maintenance and hazards associated with failure to maintain buried natural gas piping on your own property. Greenwood CPW is normally responsible for CPW-owned facilities installed in streets and easements, as well as those service lines that are installed between Greenwood CPW’s main service and the customer’s meter setting.
The gas piping located underground between Greenwood CPW gas meter and any other structure or appliance being served, as well as any underground buried branch connections from an existing customer-owned natural gas line to serve another structure or appliance on the outlet side of the meter is the responsibility of the customer.
If buried natural gas piping and other natural gas facilities are not maintained properly, they could be susceptible to potential hazards of corrosion and leakage. For buried natural gas piping on your property that is on the outlet side of the meter, you must adhere to the following:
- Buried gas piping should be:
a. Periodically inspected for leaks.
b. Periodically inspected for corrosion if the piping is metallic.
c. Repaired if any unsafe condition is discovered.
- When excavation is to occur near your buried gas piping, it should be located in advance and the excavation done by hand.
- All required record keeping mandated by State and Federal officials.
