  1. Gas Gathering Final Rule Federal Register Vol. 71, No. 50 Wednesday, March 15, 2006 Pages 13289 - 13303

  2. Why Change?

  3. Definition • As defined in §192.3 - • "Gathering Line" means a pipeline that transports gas from a current production facility to a transmission line or main.

  4. Applicability • §192.1 What is the scope of this part?(b) This part does not apply to– • (b)(4) Onshore gathering of gas– (i) Through a pipeline that operates at less than 0 psig (0 kPa); (ii) Through a pipeline that is not a regulated onshore gathering line (as determined in §192.8); and (iii) Within inlets of the Gulf of Mexico, except for the requirements in §192.612.

  5. Incorporation by Reference • §192.7 What documents are incorporated by reference partly or wholly in this part? (4) API Recommended Practice 80 (API RP 80) “Guidelines for the Definition of Onshore Gas Gathering Lines'' (1st edition, April 2000)

  6. Gas Gathering Compliance 3 Step Process: Step 1. Is it a gathering line? (Where does production stop, gathering start; where does gathering end, transmission start)

  7. Gas Gathering Compliance 3 Step Process: Step 2. If gathering, is it jurisdictional? Type A versus Type B Lines Requires Class Location Survey/ Class 2 Corridor Approach

  8. Gas Gathering Compliance 3 Step Process: Step 3. If jurisdictional, what regulations apply? Type A versus Type B Higher Risk/Lower Risk Compliance Dates

  9. §192.8 How are onshore gathering lines and regulated onshore gathering lines determined? (a) An operator must use API RP 80 (incorporated by reference, see §192.7), to determine if an onshore pipeline (or part of a connected series of pipelines) is an onshore gathering line. The determination is subject to the limitations listed below. After making this determination, an operator must determine if the onshore gathering line is a regulated onshore gathering line under paragraph (b) of this section.

  10. Beginning of Gathering §192.8(a)(1)- The beginning of gathering, under section 2.2(a)(1) of API RP 80, may not extend beyond the furthermost downstream point in a production operation as defined in section 2.3 of API RP 80.

  11. API RP 80 - Gathering Line 2.2 Onshore Gathering Line • (a) means any pipeline or part of a connected series of pipelines used to • (1) transport gas from the furthermost downstream point in a production operation to the furthermost downstream of the following endpoints, …………

  12. API RP 80 – Production Operation 2.3 “Production Operation” means piping and equipment used for production and preparation for transportation or delivery of hydrocarbon gas and/or liquids and includes the following processes: (a) extraction and recovery, lifting, stabilization, treatment, separation, production processing, storage, and measurement of hydrocarbon gas and/or liquids; and (b) associated production compression, gas lift, gas injection, or fuel gas supply.

  13. Beginning of Gathering §192.8(a)(1) This furthermost downstream point does not include equipment that can be used in either production or transportation, such as separators or dehydrators, unless that equipment is involved in the processes of “production and preparation for transportation or delivery of hydrocarbon gas'' within the meaning of “production operation.''

  14. Beginning of Gathering Meter This means: Production stops when single phase flow starts. Separator

  15. End of Gathering To determine the end point of gathering, you have to use a combination of the gathering line definition in API RP 80 with the limitations in 192.8(a)(2). The end of gathering is established by the furthermost endpoint…….

  16. API 80 - Gathering Line 2.2(a)(1)(A) • The inlet of the furthermost downstream natural gas processing plant, other than a natural gas processing plant located on a transmission line,

  17. End of Gathering – Processing Plant §192.8(a)(2) – The endpoint of gathering, under section 2.2(a)(1)(A) of API RP 80, may not extend beyond the first downstream natural gas processing plant, unless the operator can demonstrate, using sound engineering principles, that gathering extends to a further downstream plant.

  18. API 80/Part 192 Combined – Processing Plant

  19. API 80 – Gas Treatment 2.2(a)(1) • (B) the outlet of the furthermost downstream gathering line gas treatment facility,

  20. API RP 80 - Gas Treatment 2.2.1.2.2 Gas Treatment • Gas treatment often occurs in conjunction with gas processing or compression and in such cases is considered to be part of those operations. In some cases, however, gas treatment operations involve significant stand-alone facilities (e.g., a sulfur recovery or large dehydration facility).

  21. End of Gathering – Gas Treatment §192.8(a) Regulation is silent on a limitation, but from the preamble of the final rule – this endpoint refers to a “gas treating plant” in the RP as significant stand-alone facilities (e.g., a sulfur recovery or large dehydration facility) or similar facility and is not intended to be a simple piece of equipment like a separator or dehydrator.

  22. API 80 – Commingling 2.2(a)(1) • (C) the furthermost downstream point where gas produced in the same production field or separate production fields is commingled,

  23. End of Gathering - Commingling §192.8(a)(3) – If the endpoint of gathering, under section 2.2(a)(1)(C) of API RP 80, is determined by the commingling of gas from separate production fields, the fields may not be more than 50 miles from each other, unless the Administrator finds a longer separation distance is justified in a particular case (see 49 CFR §190.9).

  24. API 80/Part 192 Combined – Commingling 2.2(a)(1) • (C) the furthermost downstream point where gas produced in the same production field or separate production fields is commingled, but the fields may not be more than 50 miles from each other

  25. End of Gathering - Commingling But… PHMSA also considers the point of commingling on the line can’t be more than 50 miles

  26. Point “A ” to Point “B” – 2 miles Point “B ” to Point “C” – 42 miles Production Field “C” Production Field “A” 15 Miles Endpoint of Gas Gathering Point “B” Transmission Pipeline Point “C” 30 Miles Point “A” Production Field “D” 10 Miles LEGEND Transmission Pipeline Production Field “B” Gathering pipeline

  29. API 80 – Compressor 2.2(a)(1) • (D) the outlet of the furthermost downstream compressor station used to lower gathering line operating pressure to facilitate deliveries into the pipeline from production operations or to increase gathering line pressure for delivery to another pipeline, or

  30. End of Gathering - Compressor §192.8(a)(4) – The endpoint of gathering, under section 2.2(a)(1)(D) of API RP 80, may not extend beyond the furthermost downstream compressor used to increase gathering line pressure for delivery to another pipeline.

  31. API 80/Part 192 Combined - Compressor 2.2(a)(1) • (D) the outlet of the furthermost downstream compressor station used to lower gathering line operating pressure to facilitate deliveries into the pipeline from production operations or to increase gathering line pressure for delivery to another pipeline, or No change…..

  32. What are regulated segments? • (b) For purposes of §192.9, “regulated onshore gathering line'' means: • (1) Each onshore gathering line (or segment of onshore gathering line) with a feature described in the second column that lies in an area described in the third column; and • (2) As applicable, additional lengths of line described in the fourth column to provide a safety buffer:

  33. Categories of Gathering Lines • Type “A” • => 20% SMYS; or • Above 125 psig for non-metallic • Type “B” • < 20% SMYS; or • At or below 125 psig for non-metallic

  34. Regulated Type A • Type “A” • => 20% SMYS; or • Above 125 psig for non-metallic • Located in Class Locations 2, 3 and 4

  35. Regulated Type B • Type “B” • < 20% SMYS; or • At or below 125 psig for non-metallic • Area 1 - Located in Class Locations 3 and 4 • Area 2 - Located in Class Location 2

  36. Regulated Type B – Area 2 Determinations (a) A Class 2 location.(b) An area extending 150 feet on each side of the centerline of any continuous 1 mile of pipeline and including more than 10 but fewer than 46 dwellings.

  37. Regulated Type B – Area 2 Determinations (c) An area extending 150 feet on each side of the centerline of any continuous 1000 feet of pipeline and including 5 or more dwellings.

  38. Compliance Activities • Type “A” • All transmission line activities required by Part 192 except IM and ILI passage capability

  39. Compliance Activities • Type “A” • However, an operator of a Type A regulated onshore gathering line in a Class 2 location may demonstrate compliance with subpart N by describing the processes it uses to determine the qualification of persons performing operations and maintenance tasks

  40. Compliance Activities • Type “B” • If a line is new, replaced, relocated, or otherwise changed, the design, installation, construction, initial inspection, and initial test must be in accordance with this part for transmission lines. • March 15, 2007

  41. Compliance Activities • Type “B” • If the pipeline is metallic, control corrosion according to Subpart I • Damage Prevention Program under §192.614 • Establish the MAOP of the line under §192.619 • Line marking for transmission lines in §192.707; • Public Education Program under §192.616

  42. Compliance Deadlines ~192.9(e)

  43. Compliance Deadlines If, after April 14, 2006, a change in class location or increase in dwelling density causes an onshore gathering line to be a regulated onshore gathering line, the operator has 1 year for Type B lines and 2 years for Type A lines after the line becomes a regulated onshore gathering line to comply with this section
