SHEILA L. DELANEY,
Plaintiff-Appellant,
v. No. 98-7109
(D.C. No. CV-97-145-S)
KENNETH S. APFEL, Commissioner, (E.D. Okla.)
Social Security Administration,
Defendant-Appellee.
ORDER AND JUDGMENT *
Before PORFILIO , McKAY , and LUCERO , Circuit Judges.
After examining the briefs and appellate record, this panel has determined
unanimously to grant the parties’ request for a decision on the briefs without oral
argument. See Fed. R. App. P. 34(f); 10th Cir. R. 34.1(G). The case is therefore
ordered submitted without oral argument.

This order and judgment is not binding precedent, except under the
doctrines of law of the case, res judicata, and collateral estoppel. The court
generally disfavors the citation of orders and judgments; nevertheless, an order
and judgment may be cited under the terms and conditions of 10th Cir. R. 36.3.
Plaintiff Sheila L. Delaney appeals from the denial of supplemental security
income (SSI) benefits. She asserts that the administrative law judge (ALJ) erred
in the three-phase analysis at step four of the evaluation sequence. See generally
Williams v. Bowen , 844 F.2d 748, 750-52 (10th Cir. 1988). We have jurisdiction
under 28 U.S.C. § 1291 and 42 U.S.C. § 405(g), and reverse.
Plaintiff was born on May 14, 1960. She completed high school and one
year of appliance repair training. In October 1988, she injured her right knee in
a fall at work and required orthopedic surgery. She has reinjured the same knee
twice since then, but has not needed additional surgery. She claims that both of
her knees hurt if she stands for more than fifteen minutes. Plaintiff is also
morbidly obese and claims back problems, vertigo, pain in her head, and difficulty
concentrating. She alleges that she has been disabled since September 1990.
The ALJ concluded summarily at step three that plaintiff’s impairments
were not equivalent to any of the listed impairments. See Williams , 844 F.2d
at 751. He decided at step four that she retained the residual functional capacity
(RFC) for light work limited by a need to alternate sitting and standing, that her
past job as a security guard did not demand more than that, and that she could
therefore return to her past job as she actually had performed it.

We review the agency’s decision on the whole record to determine only
whether the factual findings are supported by substantial evidence and the correct
legal standards were applied. See Goatcher v. United States Dep’t of Health
& Human Servs. , 52 F.3d 288, 289 (10th Cir. 1995). We may not reweigh the
evidence or substitute our judgment for that of the agency. See Kelley v. Chater ,
62 F.3d 335, 337 (10th Cir. 1995).
At step four, an SSI claimant bears the burden of proving that her medical
impairments prevent her from performing work that she has performed in the past.
See 20 C.F.R. § 416.920(e); Williams , 844 F.2d at 751 & n.2. A claimant is not
disabled if she fails to prove that she does not retain the RFC to perform “the
actual functional demands and job duties of a particular past relevant job.” Social
Security Ruling 82-61, 1982 WL 31387, at *2.
However, in order to make the ultimate finding that a claimant is not
disabled at step four, the ALJ is required by the agency’s own rulings to make
specific and detailed predicate findings concerning the claimant’s residual
functional capacity, the physical and mental demands of the claimant’s past jobs,
and how these demands mesh with the claimant’s particular exertional and
nonexertional limitations. See Social Security Ruling 96-8p, 1996 WL 374184,
Social Security Ruling 82-62, 1982 WL 31386, at *4; see also Winfrey v. Chater ,
-3-
92 F.3d 1017, 1023-25 (10th Cir. 1996). The ALJ is bound by the agency’s
rulings. See 20 C.F.R. § 402.35(b)(1).
Plaintiff argues that the ALJ erred: (1) by improperly discounting the
severity of her right knee impairment as part of his determination that she can
perform light work, while ignoring that she was close to meeting one of the
obesity listings based on her knee impairment, and improperly assuming that she
could and should have lost weight; (2) by failing to develop the record regarding
the amount of walking and standing her past job demanded, which, she argues,
was required to properly support his findings concerning her ability to return to
that job; and (3) by improperly basing subsequent required findings on his prior,
flawed analysis. We agree.
The ALJ failed to make all of the detailed findings required by the
regulations and rulings at step four. As a result, his conclusions are not supported
by substantial evidence. In evaluating plaintiff’s RFC at the first phase of step
four, the ALJ failed to assess plaintiff’s ability to perform each of the seven
strength demands (sitting, standing, walking, lifting, carrying, pushing, and
pulling) and to carefully compare her restrictions with the functional demands
of light work as defined by the regulations. See 20 C.F.R. §§ 416.945(b),
416.967(b); Social Security Ruling 96-8p, 1996 WL 374184, at *3, *5. Because
plaintiff’s main impairments are morbid obesity and a knee problem, it was error
-4-
for the ALJ to fail to address the effect of these impairments on her ability to
stand or walk for the greater part of an eight-hour workday.
The ALJ also erred at phase one by exaggerating the extent of plaintiff’s
daily activities. For example, plaintiff testified that she visited friends once or
twice a week. See Appellant’s App., Vol. II, at 47. The ALJ stated, however,
that plaintiff went out with friends several times a week. See id. at 17. Plaintiff
testified that she drove once a week. See id. at 47. The ALJ stated that she drove
wherever she needed to go. See id. at 17. Plaintiff testified that her daughters
did their home-schooling primarily on their own and that she did not remain
seated during their two-hour morning and afternoon sessions. See id. at 44-45.
The ALJ stated that plaintiff presumably sat for the duration of the girls’
schoolwork each day. See id. at 17. This is not meant to be a comprehensive
list of the ALJ’s exaggeration of the record, but only to provide examples of
the error.
Plaintiff also argues that she was only a few pounds shy of meeting
a listing for obesity and being presumptively unable to perform even a substantial
number of sedentary jobs. She therefore questions the ALJ’s determination at
phase one of step four that she could perform light work. We find this argument
to be without merit, as plaintiff lacks evidence of a history of limitation of motion
in her knee that is required by the listing. See 20 C.F.R. pt. 404, subpt. P, app. 1,
-5-
§ 9.09(A). It does appear that, in making his RFC determination, the ALJ
improperly relied in part on his belief that plaintiff should have lost weight,
without pointing to evidence that she was capable of losing weight or that any of
her doctors had recommended to her that she lose weight. See Appellant’s App.,
Vol. II, at 18.
At phase two, the ALJ also failed to adequately inquire into the demands
of plaintiff’s past job as a security guard. He focused on her ability to lift the
required weight and sit for certain tasks, but failed to find out how much walking
and standing were required. This also was error. It follows that the ALJ’s
ultimate conclusion, at phase three, that plaintiff could return to this past job was
tainted by his failure to develop an adequate record. See Henrie v. United States
Dep’t of Health & Human Servs. , 13 F.3d 359, 360-61 (10th Cir. 1993).
The judgment is REVERSED and the case is REMANDED with directions
to remand to the agency for additional proceedings consistent with this order and
judgment.
