  Based on the use of contour gauge and collinear factorization, we propose a
new set of single spin asymmetry which can be measured in polarized Drell-Yan
process by SPD@NICA. We stress that the discussed single transverse spin
asymmetries exist owing to the gluon poles manifesting in the twist-3 or
twist-2$\otimes$twist-3 parton distributions related to the
transverse-polarized Drell-Yan process.
