Saltwater Disposal Well

I have been approached by a company to have a saltwater disposal well on my property.

I am unfamiliar with what is typically paid, what to watch out for in the agreements and what it should include and what may be the typical barrels/day disposal rate.

Any help with what the typical rates are for $/barrel of saltwater, $/rod for right-of-ways (pipeline, electric, polyline, road), $ for well site pads (5ac) and facility pads. Typical term of this type of agreement (5 years?), are there typically annual rental charges, minimum royalty amounts, etc.

Any help with this or a sample agreement would be greatly appreciated.

Thanks!
