Black lung disease cases in coal miners have been increasing since 2000 for uncertain reasons.

The number of earthquakes of magnitude 3 or greater in the central and eastern US has increased significantly in recent years, from about 21 a year between 1967 and 2000, to over 300 between 2010 and 2012. Most of this increase seems to be linked to the deep injection of wastewater in underground wells, according to a recent review of seismic activity.

A positive response notification to provide information regarding locate and/or marking operations for underground facilities may include time-stamp information to provide proof of a time at which the locate and/or marking operation was completed by a locate technician, and/or place-stamp information to provide proof of a presence of the locate technician at or near a work site. An electronic manifest image and/or a virtual white line image similarly may be included in a positive response notification. In one example, such images may be bundled together based on respective descriptor files (or descriptor metadata) that associates the corresponding images with a locate request ticket for the operation. In another example, a positive response notification may include environmental information regarding one or more environmental conditions present at or near the work site during the locate and/or marking operation.

Generating a corrected electronic record of a locate and/or marking operation. The operation comprises locating and/or identifying, using a physical locate mark, presence or absence of an underground facility within a dig area. At least a portion of the dig area may be excavated or disturbed. First information relating to a location of the facility and/or the mark is received. Based at least in part on the first information, the location of the facility and/or the mark is represented to generate an electronic visual representation of the operation. Second information relating to a corrected location of the facility and/or the mark is received. Based at least in part on the second information, the corrected location is represented to generate a corrected electronic visual representation of the operation. Third information relating to the corrected representation of the operation is transmitted and/or stored to generate the corrected electronic record of the operation.

A method is disclosed for assessing an aspect relating to a locate and/or marking operation performed by a locate technician based on an electronic representation of the operation. The operation includes locating and/or identifying, using a physical locate mark, a presence or an absence of an underground facility within a dig area. A portion of the dig area may be excavated or disturbed during excavation activities. The method includes digitally representing, on a display device, the facility and/or the physical locate mark to generate an electronic visual representation of the operation. The method further includes determining a length associated with a portion of the digitally represented facility and/or physical locate mark in the electronic visual representation of the operation. The method further includes, based on the determined length, automatically assessing the aspect relating to the operation.

Generating a digital-media-enhanced electronic record of a locate and/or marking operation performed by a locate technician. The locate and/or marking operation comprises locating and/or identifying, using at least one physical locate mark, a presence or an absence of at least one underground facility within a dig area, wherein at least a portion of the dig area may be excavated or disturbed during excavation activities. A location of the at least one underground facility and/or the at least one physical locate mark is electronically rendered on a display device so as to generate an electronic visual representation of the locate and/or marking operation. At least one digital media file representation of a corresponding digital media file relating to at least one aspect of the locate and/or marking operation or an environment of the dig area is also electronically rendered on the display device, so as to generate a digital-media-annotated representation of the locate and/or marking operation. Information relating to the digital-media-annotated representation of the locate and/or marking operation is electronically transmitted and/or stored so as to generate the digital-media-enhanced electronic record of the locate and/or marking operation.

Various embodiments of the present invention provide adjustable pit liners for use in conjunction with pipelines installed underground. The pit liners provide surface access to devices in fluid communication with the pipeline. The adjustability of the pit liners facilitates installation of the pit liners before the final grade surrounding the pit is known. In various embodiments, a tubular structure having an upper section and a lower section is provided, wherein the upper section and the lower section are slideably connected in a telescoping relationship. A locking mechanism is also provided to releaseably lock the overall height of the tubular structure as desired.

‘Underground Thermal Battery Storage System’ using a battery structure of one or more underground thermally insulated cells, where each cell comprised of a waterproof thermal insulation shell, one or more fluid storage tanks and earth matrix. The thermal storage cell's fluid storage tanks are interconnected using a thermal fluid transport system with control valves, circulating pumps, and managed by a programmable controller. The programmable controller uses the cell sensors to determine cell status, control cell interconnections, and to manage the thermal charging and discharging by exterior heating or cooling devices. A moisture injection system is provided to control the thermal conductivity within the cell's earth matrix.

Methods, processes, compositions and systems for preventing leaching effects from water pipes (such as lead, steel and copper) having an inner diameter of at least approximately 12 mm. 2-part thermoset resin coating is applied to the inner surfaces of the pipes where the curing agent can be a phenol free and plasticizer free adduct type. The coating can reduce heavy metals, such as lead, from leaching from installed pipes to less than approximately 10 μg/L (10 ppb). When cured, specific leachates, Bisphenol A and Epichlorohydrin from the coatings will be (less than)
