The Astronomical Roentgen Telescope X-ray Concentrator (ART-XC) instrument onboard the Spectrum RöntgenGamma (SRG) mission began the all-sky hard X-ray survey 08 December 2019 and has already completed onecomplete scan of the sky. The observations of the ecliptic pole regions will reach exceptional depth thanks to thesurvey design of overlapping exposure in these regions. In anticipation of the ART-XC survey in the North Ecliptic Pole(NEP) region, we explore publicly available multiwavelength catalogs in the NEP region and investigate AGNcandidates that might exhibit hard X-ray signals that will be detected by ART-XC. To capitalize on the ART-XCcoverage in the NEP region, we also investigate ART-XC cadence and sensitivity limits for a selected few luminousX-ray sources. Comparisons between our simulations and the ART-XC survey data in NEP will also be discussed
