CFC · California Fire Code

Which referenced standards cover petroleum storage, welding and tank protection?

Q: Which standard do I use for safe entry and cleaning of petroleum tanks?

The Code directs safe entry and tank cleaning to API Std 2015 via § 5706.7.2 .

Q: Where does the CFC point me for underground tank closure procedures?

For UST closure the controlling reference is API RP 1604 , cited by § 5704.2.13 .

If you operate or work on petroleum tanks, the California Fire Code points you to specific API and API Recommended Practice documents: follow the API standards named in **§ 5706.7** for refineries/above‑ground tank welding, corrosion protection, inspection, safe entry and overfill protection, and follow **API RP 1604** (and RP 1615 where cited) for underground tank closure and installation as required by **§ 5704.2.13**.

What the code requires — 2-4 sentences

The California Fire Code requires that petroleum-processing plants and facilities, and related tank work, comply with the specific industry standards listed in § 5706.7 for refineries and commercial petroleum operations and with underground‑tank closure/installation standards referenced by § 5704.2.13 for underground petroleum storage tanks. In plain English: follow the named API / RP standards for welding, hot tapping, corrosion protection, inspection, overfill protection and tank closure/installation when the Code points to them. See § 5706.7 and § 5704.2.13 for the controlling references.

If you operate, repair, enter, weld on, or close petroleum storage tanks at a commercial/refinery scale, the CFC directs you to comply with the specific API / RP standards listed in § 5706.7 (aboveground/refinery matters) and RP 1604 / RP 1615 for underground‑tank closure/installation per § 5704.2.13.

Requirements in detail

Which standards are named by the Code

For refineries and petroleum-processing facilities (above‑ground tanks, hot work at refineries, inspection, corrosion protection, overfill, etc.), the Code explicitly ties those operations to API and API RP documents in § 5706.7. The Code text names: API 651, API 653, API 752, API 1615, API 2001, API 2003, API 2009, API 2015, API 2023, API Publ 2201, and API 2350 as the referenced standards.
For underground petroleum storage tank (UST) closure and installation, the Code references industry recommended practices: API RP 1604 — Closure of Underground Petroleum Storage Tanks and API RP 1615 — Installation of Underground‑Petroleum Storage Systems under § 5704.2.13 (and related subsections).

What each referenced standard covers (short, decision‑relevant)

Use the table below to match the practical decision to the CFC reference and the standard the Code points you to.

Decision / topic	Referenced standard (title)	What the standard controls (short)	Code Reference
Welding / hot‑tapping on equipment in service	API Publ 2201 — Procedures for Welding or Hot Tapping on Equipment in Service	Procedures and safety for welding/hot‑tapping on in‑service equipment (used for refinery/hot‑work at petroleum facilities)	§ 5706.7
Safe welding and cutting practices in refineries	API RP 2009 — Safe Welding and Cutting Practices in Refineries, Gas Plants & Petrochemical Plants	Safe hot‑work practices specific to refinery/process environments	§ 5706.7
Corrosion protection of above‑ground tanks	API RP 651 — Cathodic Protection of Aboveground Petroleum Storage Tanks	Cathodic protection design/installation to control corrosion of tanks and piping	§ 5706.7
Tank inspection, repair, reconstruction	API Std 653 (and addenda) — Tank Inspection, Repair, Alteration and Reconstruction	In‑service inspection and repair criteria for above‑ground storage tanks	§ 5706.7
Safe entry / cleaning of tanks	API Std 2015 — Requirements for Safe Entry and Clearing of Petroleum Storage Tanks	Procedures and controls for confined‑space entry and cleaning of petroleum tanks	§ 5706.7
Storage of heated asphalt/crude residues	API RP 2023 — Guide for Safe Storage and Handling of Heated Petroleum‑Derived Asphalt Products and Crude‑Oil Residue	Safe handling and storage practices for heated petroleum residues	§ 5706.7
Overfill protection for storage tanks	API Std 2350 — Overfill Protection for Storage Tanks in Petroleum Facilities	Overfill prevention system requirements and test/inspection guidance	§ 5706.7 (also referenced elsewhere for overfill)
Closure of underground tanks	API RP 1604 — Closure of Underground Petroleum Storage Tanks	Procedures for removal, abandonment in place, assessment and documentation for UST closure	§ 5704.2.13
Installation of underground tank systems	API RP 1615 — Installation of Underground‑Petroleum Storage Systems	Installation practices, materials and testing for UST systems	§ 5704.2.13.1.5 and § 5706.7 (as applicable)

Notes:

The Code text of § 5706.7 lists the API standards above as the required references for refinery/petroleum processing operations.
§ 5704.2.13 directs closure/related procedures for underground petroleum storage to RP 1604 (and cross‑references RP 1615 for installation).

Where welding/hot work rules also live in the Code

Chapter 35 (Welding and Other Hot Work) contains general hot‑work safety, permit and procedural requirements; when the operation involves petroleum equipment at refineries, the API documents named in § 5706.7 apply as the specialized technical standards. The code’s referenced‑standards list ties the industry API documents into those special operations.

Exceptions & special cases

The CFC text we retrieved names the standards but does not reproduce the full requirements of those standards; the Code requires compliance with the standards “in accordance with” the sections cited (e.g., § 5706.7), meaning the detailed procedures and tests are in the API / RP documents themselves. For the specific procedures (test methods, sample sizes, instrumentation, intervals, forms), you must consult the named standard editions.
For underground tanks, § 5704.2.13 points to RP 1604 for closure — whether removal or abandonment in place — but the CFC text does not list the step‑by‑step closure procedures (those are in RP 1604). If you need the exact sampling or remediation actions, use RP 1604.
Some related activities (overfill protection, venting, piping vent standards) are referenced elsewhere in the Code (for example, overfill protection also appears connected to other sections such as § 5704.2.7.5.8). Cross‑check those sections when the decision depends on siting, venting or piping details.

Common mistakes

Applying only the general hot‑work Chapter 35 procedures and ignoring the refinery‑specific API documents named in § 5706.7. The Code expects the API/RP technical standards for petroleum operations to be followed in addition to the general hot‑work rules.
Assuming “underground tank closure” requirements are fully contained in the CFC text — the CFC delegates the technical closure steps to API RP 1604, so relying only on the CFC text can miss critical procedural steps.
Using the wrong edition/version of a referenced standard. The Code’s referenced‑standards list ties specific editions to sections; always confirm which edition the jurisdiction enforces. The referenced standards list in the CFC names editions alongside the standards.

Worked example — concrete scenario

Scenario: An operator is retiring a 10,000‑gallon underground gasoline tank at a commercial fueling site and plans to remove it.

The Fire Code directs closure of underground petroleum storage tanks in § 5704.2.13 and points to API RP 1604 — Closure of Underground Petroleum Storage Tanks for the procedures. That means the operator must follow RP 1604 for steps such as pre‑closure assessment, sampling, removal methods, and documentation.
If the site also includes above‑ground piping / tanks that will be entered or welded during removal, § 5706.7 requires the applicable API hot‑work and safe‑entry standards (for example, API Publ 2201 for welding/hot‑tapping on equipment in service and API Std 2015 for safe tank entry/cleaning) to be followed for those operations. The operator must implement the safe‑entry procedures and the welding/hot‑tapping controls in those API documents in addition to any local hot‑work permit per Chapter 35.

Bottom line: before removal, procure RP 1604 and the named API standards (2015, 2201, etc.), follow their step‑by‑step procedures, and document compliance to satisfy the requirements invoked by § 5704.2.13 and § 5706.7.

Related provisions (CFC sections)

§ 5706.7 — Refineries; lists the API standards that apply to refinery and commercial petroleum operations.
§ 5706.7.1 — Corrosion protection (points to API 651).
§ 5706.7.2 — Cleaning of tanks (points to API 2015).
§ 5706.7.3 — Storage of heated petroleum products (points to API 2023).
§ 5704.2.13 — Closure of underground petroleum storage tanks (points to API RP 1604).
Chapter 35 (Welding and Other Hot Work) — general hot‑work rules that apply in addition to the API standards for petroleum operations.
Overfill protection references (examples at § 5704.2.7.5.8, § 5706.4.6) — which point to API Std 2350 for overfill protection design/tests.

If you need, I can:

Pull the exact edition and publisher details for a specific API/RP listed in § 5706.7 or § 5704.2.13 (the CFC referenced‑standards table includes edition info), or
Summarize the scope of a particular API document (for example, API RP 1604 or API Publ 2201) based on the standard’s table of contents — but that requires consulting the standard itself (not fully reproduced in the CFC).

Frequently asked questions

Which section of the CFC names the industry standards for refineries and petroleum processing?

The Code names the API / RP documents that apply to refineries and petroleum processing in § 5706.7.

Which standard do I use for safe entry and cleaning of petroleum tanks?

The Code directs safe entry and tank cleaning to API Std 2015 via § 5706.7.2.

Where does the CFC point me for underground tank closure procedures?

For UST closure the controlling reference is API RP 1604, cited by § 5704.2.13.

Does Chapter 35 hot‑work guidance replace the API standards for refinery welding?

No. Chapter 35 provides general hot‑work rules; when the operation involves refinery or commercial petroleum equipment the Code requires compliance with the specific API standards named in § 5706.7 in addition to Chapter 35.

The Code names an API standard — do I need to buy it?

Yes. The CFC references these industry standards by name; the detailed technical procedures and tests are in the standards themselves (API/RP documents), which you must obtain to fully comply. The CFC lists the standards and their editions in its referenced‑standards tables.
