In November 1989 Charles E. Hajek applied for disability insurance benefits and Supplemental Security Income under the Social Security Act. After Hajek requested and received a hеaring, an administrative law judge (ALJ) denied benefits. The Appeals Council denied review, so the ALJ’s decision became the final decision of the Secretary of Health and Human Services (Secretary). Hajek then brought suit in federal court. The case was referred to a magistrate judge, who recommended that the Secretary’s decision be affirmed. After the distriсt court adopted this recommendation, Hajek appealed to this court. We reverse and remand.
I.
Hajek is a sixty year old male who previously worked as a school custodian (i.e. janitor). In November 1984 he entered a hospital for severe chest pain, and cardiac cathet-erization revealed severe coronary artery disease. He therefore underwent bypass surgery on November 28, 1984. In September 1985 he was in a hospital for repair of an incisional hernia. There were no complications related to either of these surgeries. In December 1985 Hajek again returned to the hospital after suffering chest pain. Tests indicated no major problems, and after learning Hаjek had been involved in an automobile accident in which he struck his chest on the steering wheel, his physician diagnosed a probable acute myocardial contusion. Therе is no evidence of any further treatment regarding Hajek’s heart condition or hernia repair until he was examined following his application for benefits in November 1989.
Hajek returned to work sometime in 1985 and remained until November 12, 1987, the date on which he claims he became disabled. He testified before the ALJ that he had to leave his job because of extrеme pain and fatigue in his left arm and left leg. He also testified to being unable to walk more than sixty or seventy yards at a time, to stand more than twenty minutes without fatigue, or to lift more than five or six pounds. He claimed he suffered daily pain in his chest and legs and pain in his arm about twice a month. He takes aspirin and nitrostat but no other medications because of side effеcts such as depression and disorientation.
The ALJ found that Hajek had a history of coronary artery disease, hernia repair, and chronic obstructive pulmonary disease. Hоwever, he rejected Hajek’s subjective complaints of chronic fatigue and weakness, shortness of breath, and pain. He then determined that Hajek’s residual functional cаpacity precluded heavy lifting or prolonged walking. Though Hajek could not return to the specific janitorial position he previously occupied, in that it required heavy lifting аnd prolonged walking, the ALJ concluded that he could perform “janitorial work as it is usually performed in the national economy, which requires only medium lifting and no prolonged walking.” The ALJ therefore concluded Hajek was not disabled under the Social Security Act.
While this case was pending in the district court, Hajek filed a second application for benefits. Uрon review of that application, the Secretary determined that Hajek was indeed disabled and had been so since January 14, 1991. When the Secretary’s counsel in this case lеarned of the award, he filed a motion to dismiss the present appeal, claiming Hajek abandoned review of his first application when he accepted without appeal the determination made in his second application. Since oral argument, the Secretary has moved to withdraw the motion to dismiss, and the court hereby grants that requеst. We note that the issue of disability is now moot. The only remaining issue pertains to the disability onset date. Hajek claims it is November 14, 1987; the Secretary claims it is January 14, 1991.
II.
On appeal Hajek contends the ALJ erred by failing to consider his impairments in combination and by rejecting the credibility of his testimony. He also challenges the ALJ’s finding that he could return to janitorial work as it is usually рerformed in the national economy.
Generally, our review is limited to determining whether the ALJ’s decision is based on a correct view of the law and is supported by substantial evidenсe on the rec
*92
ord as a whole.
Jackson v. Bowen,
Hajek first argues the ALJ failed to consider the combined effects of his impairments as required by 42 U.S.C. § 423(d)(2)(B). However, as noted by the magistrаte judge, Hajek’s conelusory statement is unfounded. In particular, the ALJ found that
the claimant has a history of coronary artery disease, hernia repair, and chronic obstructive pulmonary disease, but that he has not had an impairment or combination of impairments listed in, or medically equal to one listed in Appendix 1, Subpart P, Regulations No. 4.
Moreover, whеn discrediting Hajek’s allegations of pain, the ALJ noted that “the evidence as a whole does not show that the claimant’s symptoms ... preclude his past work as a janitor.” (Emphasis added.) The ALJ reiterated this conclusion in his findings when he stated that “[t]he claimant’s impairments do not prevent him from performing janitorial work ...” (emphasis added). Based on these statements, we believe the ALJ properly considered the combined effects of Hajek’s impairments.
Hajek next contends the ALJ improperly rejected the credibility of his testimony because the ALJ failed to evaluate all of the evidence as required by
Polaski v. Heckler,
Hajek next contests the ALJ’s findings regarding his residual functionаl capacity. His argument focuses on inconsistencies between two of the ALJ’s findings. In particular, he claims the ALJ’s conclusion that he could perform janitorial work was error in fight оf the underlying finding that he could not engage in prolonged walking. We agree.
Janitorial work is classified as medium in exertional requirements.
Selected Characteristics of Occupations Defined in the Dictionary of Occupational Titles,
U.S. Department of Labor (1981). 20 C.F.R. § 404.-1567(e) states that “[mjedium work involves lifting no more than 50 pounds at a time with frequent lifting or carrying of objects weighing up to 25 pounds.” Social Security Ruling (SSR) 83-10 elaborates on this definition as follows: “A full range of medium work requires standing or walking, off and on, for a total of approximately 6 hours in an 8-hour workdаy in order to meet the requirements of frequent lifting or carrying objects weighing up to 25 pounds.” This ruling is as binding on the Secretary as the regulation on which it is based. 20 C.F.R. § 422.406(b)(1);
see also Carter v. Sullivan,
Giving full effect to SSR 83-10, we must conclude that janitorial work requires walking or standing for six of the eight hours in a workday. Moreover, though the term “prоlonged walking” is admittedly vague, we believe any job requiring a person to be on his or her feet seventy-five percent of the time inevitably requires such exertion. It necessarily follоws that, contrary to the findings of the ALJ, janitorial work does indeed require prolonged walking. The ALJ therefore *93 erred in concluding that Hajek could perform his past relevant work as а janitor.
Because Hajek could not do his past relevant work, the ALJ should then have shifted the burden of proof to the Secretary to establish that Hajek could perform othеr jobs in the national economy.
Emm v. Shalala,
Accordingly, we reverse and remand to the district court with instructions to remand this case to the Secretary for a determination whether Hajek had the residual functional capacity to perform other substantial gainful activity.
