        {
            SPSite site = properties.Web.Site;
            SPUserToken sysToken = site.SystemAccount.UserToken;
            site.Dispose();

            using (var systemSite = new SPSite(properties.SiteId, sysToken))
            {
                using (SPWeb sysWeb = systemSite.OpenWeb(properties.Web.ID))
                {
                       // Code goes here 
                }
            }
