I have always been under the impression that for existing dwellings, the distance requirement is 300' for active wells and 75' for new or proposed construction as indicated below. #1 does not specify an operating well, only an active or planned drilling site for existing dwellings. Subject property (existing) is located approximately 150' from an operating oil well. I would not consider an active well to be a drilling site as no drilling is taking place.

I asked HUD and I received a different statement than indicated in the handbook which is also noted below.

So my question is: is it 75' or 300'? Thanks for the help.

1. Existing Construction
No existing dwelling may be located closer than 300
feet from an active or planned drilling site. Note
that this applies to the site boundary, not to the
actual well site.
2. New or Proposed Construction
If an operating well is located in a single-family
subdivision, no new or proposed construction may be
built within 75 feet of the operating well unless
mitigation measures are taken. This measure is
designed to:
o avoid nuisance during maintenance
o diminish noise levels caused by pumping
o reduce the likelihood of contamination by
potential spills

Hazards & Nuisances: Operating & Abandoned Oil and Gas Wells, Tanks & Pressure Lines

Chapter 1
Appraisal & Property Requirements
Page 1-18g

Operating and abandoned oil and gas wells pose potential hazards to housing, including potential fire, explosion, spray and other pollution. Therefore, no dwelling may be located closer than 300 feet from an active or planned drilling site or 75 feet from an operating well; this applies to the site boundary, not to the actual well location.

Underground Tanks: If there is any observable surface evidence of leakage from an underground storage tank, further analysis/testing is required.
Hydrogen Sulfide Gas: Commonly referred to as Sour Gas Wells are extremely hazardous. Please see: HUD Handbook 4150.2, Section 2-2.D. "Special Case..." for instructions.
For more information please see: HUD Handbook 4150.2, Section 2-2.D.

DISCLAIMER: All policy information contained in this knowledge base article is based upon the referenced HUD policy document. Any lending or insuring decisions should adhere to the specific information contained in that underlying policy document.
 
I believe it is 300 for existing and 75 for new new or proposed. My question is: isn't a new well an existing well?
 
How are you defining an "active" well?

A drilling rig is different from a completed well. I don't think they are referencing the drilling operation. A gas well may have nothing more than a well head. There may be a gas line that goes a mile or more to a compressor station or to separators and tanks.

Or, if there is a pump jack, it may be active. It may have tanks on the location. It's hard to say. Today these multi-well drilling pads may have 6 wells in one pad and the pads may take up 2 acres or more, far larger than old wellsites.
First is a drilling rig, second is 2 gas wells on one pad, third is oil well tanks (the pump is 100 yds. away) and there is a house directly behind the tanks (about 300' away.)

That's a pump-jack - either oil or a low pressure gas well that makes water.

The Railroad commission has a GIS system and you can locate the well name to determine what kind and if it is abandoned or not.

At least it is electric. They used to have a lot that ran on the gas from the well in huge one-lung horizontal engines and went POP -CHUG-CHUG-SQUEEK-POP-CHUG-CHUG... You could actually near the valves open and close.
 
75 feet from an operating well; this applies to the site boundary

What you have pictured is an operating well.
