Jerry Boldra
(Affirmative)
B.1.1, First sentence
Editorial There are aluminum and stainless steel tanks now . . . Delete the word "steel" from the first sentence.
Jerry Boldra
(Affirmative)
B.1.2 Editorial This paragraph lists five foundation types. However, Section B.4, second sentence says seven.
Consider resolving this difference. If the reader is familiar with tank foundations, this is not a big discrepancy. However, to the novice it is confusing . . . and API 650 is used world wide. We should be consistent and maintain creditability.
Jerry Boldra

B.2.3, sub-paragraph a

Jerry Boldra
(Affirmative)
B.2.5 Editorial Paragraph B.2.5 is similar to and related to Paragraph B.3.2
Consider combining these two paragraphs or putting them one after the other.
Jerry Boldra
(Affirmative)
Entire Appendix B
Editorial There are many paragraphs without titles or sub-titles. It would be help to everyone (experienced tank engineers and novice readers) to have more titles or sub-titles through out Appendix B. Titles or Sub-titles would also force us to better organize this Appendix.
Jerry Boldra
(Affirmative)
B.2.6 Editorial The first sentence is poorly written. "The chemistry of native soil and fill material shall consider in the foundation design."
The chemistry of THE native soil and fill material SHOULD BE CONSIDERED in t he foundation design.
Jerry Boldra
(Affirmative)
B.2.10 Editorial First sentence. "If a leak occurs in a tank bottom, the leaking material can also influence corrosion on the external side.
More commonly used terms for the "external side" are SOIL SIDE or UNDER SIDE. Consider changing "external side".
Jerry Boldra B.3.1, Editorial In my experience, "150 mm (6 inches) above the Recommend changing this to

surrounding ground" is not sufficient, especially long term. There are too many existing tanks where soil from the dike yard washes down during rain and covers the bottom extension, shell-to-bottom weld and even the lowest part of Course 1.
300 mm (12 inches). I can't find my new edition of API 651 . . . but I think there is a statement that suggests 12 inches in API 651.
Jerry Boldra
(Affirmative)
B.2.7 Editorial Paragraph B.2.7 is similar to and overlaps with Paragraph B.3.2.f.
Combine these two paragraphs or list them sequentially.
Jerry Boldra
(Affirmative)
B.3.1 last paragraph
Editorial This paragraph is one sentence. "Consideration shall be given in the design of a new tank foundation in the event . . ." It is poorly written and should not contain "shall".
1. Need to add something about "consideration" here. "Consideration" to do what ???
2. Change "shall" to "should". This is an appendix and supplemental. We can't tell the reader what or how . . . we can only offer ideas for consideration.
Jerry Boldra
(Affirmative)
B.3.2.f Editorial Sub-paragraph f, third sentence: ". . . may be determined in accordance with ASTM (157, or equivalent."
1. There is an open parenthesis after ASTM. Delete this open parenthesis. 2. Is ASTM 157 correct, or does this ASTM have a four digit designation?
Jerry Boldra
(Affirmative)
B.3.2.g Editorial The material in this paragraph would be presented in a manner that is easier to grasp and understand if it were placed in a table . . . similar to Paragraph B.2.7.
Make a table out of this paragraph.
Jerry Boldra
(Affirmative)
B.3.3 Technical This paragraph says, "During construction, the movement of equipment and materials across the grade will damage the graded surface . . ." After the pad has been completed by the foundation contractor, the tank contractor should be forbidden to bring material, equipment and workers onto the pad. The bottom plates should be laid on the pad from outside the pad. Equipment, materials and men should be allow only on the new bottom plates, not on the finished pad.
Change to: After the tank foundation pad has been completed by the foundation contractor, equipment and men are not allowed to be on the tank pad unless bottom plates have been laid down first. This prevents contamination of the tank pad with clay and other foreign materials from equipment tires, tracks and men's

B.3.4 and B.3.5 and B.3.6
Editorial These three paragraphs are in reverse chronological order.
Re-order these paragraphs in the following chronological order: B.3.6, B.3.5 and B.3.4.
Jerry Boldra
(Affirmative)
B.3.7 Editorial The first sentence is a little foggy. The clarity of the first sentence would be improved by adding "(cone up)" at the very end of the sentence.
Jerry Boldra
(Affirmative)
B.3.7 Technical I prefer "cone down" tank foundations/bottoms. More settlement in the center of a tank is less of a problem because the tank bottom retains it's slope better. Also, the reference at the end of the paragraph is incorrect. It should be 3.8, not 3.4.
A better presentation would be made by listing the benefits and disadvantages of cone up bottoms, and then the benefits and disadvantages of cone down bottoms.
Jerry Boldra
(Affirmative)
Proposed Appendix B
Editorial Someone will have to adapt this agenda item to API 650, 11th edition. We should not leave that to the printer.
Revise this agenda item to show revisions with reference to API 650, 11th edition.
Jerry Boldra
(Affirmative)
B.3.2.c Editorial This sub-paragraph is related to the NOTE after Paragraph B.3.7
Consider consolidating these two paragraphs.
Jerry Boldra
(Affirmative)
B.3.8 Editorial The clarity of the first sentence can be improved by adding four words.
As an alternative to B.3.7, the tank bottom may be sloped DOWNWARD toward a sump (CONE DOWN CONFIGURATION)
Jerry Boldra
(Affirmative)
B.3.7 Editorial Second sentence, last 7 words. Polish this wording by adding one word.
". . . 30% greater at the center than AT the shell."
Jerry Boldra
(Affirmative)
B.4 Editorial First sentence . . . the word "there" is spelled incorrectly.
Change "there" to "their"
Jerry Boldra
(Affirmative)
B.4 Editorial Clarify the beginning of the second sentence. It says, "Seven design examples are given to illustrate various
Seven design examples are given BELOW to illustrate . . ."

B.4.2.3.f Technical There are other considerations that should be part of a decision to add a spread footing. Also, an 18 inch width is arbritary.
The foundation design engineer may consider use of a spread footing design. This design can be useful to resist uplift forces and to spread the tank and product loads over a larger area.
Jerry Boldra
(Affirmative)
B.4 Technical Add a sentence suggesting design of the foundation so that the load (lb/sq. ft) under the foundation is approximately equal to the load (lb/sq. ft.) under the center of a full tank. If the bearing strength of the soil will allow, making these two loads approximately equal will promote more uniform settlement of the entire tank.
ADD: If the bearing strength of the soil will allow, the load under the tank foundation (including, roof, shell and contained liquid) should be approximately equal to the load under the center of a full tank.

B.2.1 Technical The number of borings is conservative. Typically smaller tanks should have one at the center and three equally spaced at the tank shell radius. Larger tanks may require more.
Also it is very beneficial to provide a suggested boring depth. Add depth = 1.5 x tank dia. at the center and 1.0 x tank dia. at the periphery

Technical I dont believe the Appendix needs to go into this much detail. There are differing opinions on the number of borings per tank, pending diameter. I don’t agree with the foundation drawings showing a sand or sand bitumen mix on top of the foundation and then sealed (especially if a concrete ringwall is used).
Marilyn Shores
Explorer Pipeline Company
(Affirmative)
Parargraph B2.1
Editorial The final sentence of this paragraph (after the quantity of borings) states that the borings should be on the circumference and "one close to the center of the tank foundation." The ones on the circumference would be close to the center of the foundation. I believe you meant one close to the center of the tank.
I am not sure that that "together with one or more borings" means.

650--554 Technical I applaud the attempt by Alan to improve App B in API 650 but do not agree with some assessments in the documentation or the associated drawings that have been added.
I voted negative on this ballot and due to the number of comments or challenges, I thought it more appropriate to add them to the ballot then try to spell them out in the ballot comment section. I made commnets to the word document and put my comments in a blue font and sent the word document in an E-mail as an attachment to Gordon Robertson and Alan Watson.

(Negative)
Para. B.2.1 Technical The outlined number of soil borings or CPTs seems excessive in light of more normal industry practice for such requirements for AST / foundation construction. Unless there is known, or determined, variations in sunsrface strata at the AST site, the requirement for 9 or 13 borings or CPTs for tanks from 40 ft. through 130 ft. diameter and larger is excessive and not justified. Further discussion and agreement on this requirement will be necessary within SCAST before this portion of

B.3.7 Technical I don't agree with the addition of the 30% value in the first paragraph. It could be more or less. I think this section should remain as originally worded.
Delete proposed additional "30%" and "than the tank shell".

Suggest not using a sand layer when the tank has no backing strips and sealing the edge and sloping the concrete slab down from the edge of the tank bottom. I believe that there are numerous small tanks on concrete slabs with no sand.
