A sample of 404 sources from the Bolocam Galactic Plane Survey (BGPS) 1.1mm dust clump survey that met specific Galactic Legacy Infrared Mid-Plane Survey Extraodinaire (GLIMPSE) point-source color criteria was selected and 318 of these were observed. The new observations resulted in the detection of 29 methanol masers, including 12 new ones. Together with the additional 74 detections from the literature, this means that a total of 103 methanol masers are coincident with 1.1mm dust clumps, yielding an overall detection rate of 26%. A comparison of the properties of a 1.1mm dust clump and a 6.7GHz methanol maser indicates that methanol masers with a higher flux density and/or luminosity are generally associated with more massive but less dense 1.1mm dust clumps. The overall detection rate of 26% appears to vary as a function of the derived H_2_ column density of the associated 1.1mm dust clump. The methanol masers were primarily detected toward the brighter and more massive 1.1mm dust clumps. A subsample of 194 sources that overlapped sources with observations of the 95GHz methanol line was investigated in more detail for the properties of 1.1mm dust clumps. The statistical analysis reveals that 1.1mm dust clumps with both class I and II counterparts have much higher mean and median values of mass, column density, and flux density than those with only class I or II counterparts. Based on our much larger sample, we slightly revise the boundary defined previously for selecting BGPS sources associated with a class II methanol maser, wherein ~80% of expected class II methanol masers will be detected with a detection rate in the range of 40-50%.2014A&A...563A.130Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/563/A130CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/293 : GLIMPSE Source Catalog (I + II + 3D) (IPAC 2008)J/ApJ/721/137 : The Bolocam Galactic Plane Survey (BGPS) (Bally+, 2010)J/ApJS/200/5 : 95GHz class I methanol maser survey (Chen+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/563/A130https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/563/A130http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/563/A130https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/563/A130https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/563/A130http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/563/A130GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/563/A130/tableb1 (Parameters of the target Bolocam Galactic Plane Survey (BGPS) and GLIMPSE sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/563/A130/tableb1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/563/A130/tableb1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/563/A130/tableb1?GETtext/xml+votable180.050000true269.1054167-25.05105560.0055555555555555565/7278 7377 7383 7564 7605 6/12970 12974 14352-14353 14355 14403 28901 28912-28913 28916 28918-28919 29090-29091 29096-29097 29100-29101 29103 29116 29118-29119 29457 29461 29504-29505 29507 29517 29522 29528-29529 30218-30219 30222 30241 30244-30245 30262-30263 30268-30269 30312-30313 30315-30316 30318-30319 30330 30405 30416-30417 30419 30594-30595 30600 30606 30616 30618-30619 30622-30623 30641 30645 30691-30692 30694-30695 30701 30716-30717 307191.8058623843283312e-22 5.517906024225661e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/563/A130?format=asciiRadiodefaultJ/A+A/563/A130/tableb1Parameters of the target Bolocam Galactic Plane Survey (BGPS) and GLIMPSE sourcesPID[1031/6501] ID number of BGPS source (from Rosolowsky et al., 2010, Cat.
