evidence of any racial element to either event. The Supreme Court has instructed courts not to use the discrimination laws as a “general civility code,” see Faragher, 524 U.S. at 787, 118 S.Ct. 2275, and these incidents as alleged by plaintiff are not enough to rise above the level of “merely offensive” into the category of a discriminatory, abusive, hostile work environment.
The same cannot be said of the Ku Klux Klan letter, which is plainly serious and extremely offensive. That is true even though it was not specifically directed to, or left on the desk of, plaintiff, because it is patently hostile to all AID African-American employees. But it is only a single offensive act, and hence may be “simply insufficiently severe to create an abusive working environment.” Glovinsky v. Cohen, 983 F.Supp. 1, 3-4 (D.D.C.1997). A court must consider the frequency of any discriminatory conduct, and a workplace is “hostile” only when it is permeated with discriminatory intimidation, ridicule, and insult. Oncale, 523 U.S. at 81, 118 S.Ct. 998; Faragher, 524 U.S. at 787, 118 S.Ct. 2275; Harris, 510 U.S. at 21, 114 S.Ct. 367; see also Breeden, 532 U.S. at 271, 121 S.Ct. 1508 (isolated incidents normally insufficient); Neuren, 43 F.3d at 1513. Standing alone, then, the single incident of this offensive letter is not enough to create a pervasive hostile work environment actionable under Title VII, notwithstanding its seriousness as an isolated event.
An important element of the analysis, moreover, is whether the employer knew of the alleged harassment and failed to take prompt and effective measures in response. See Ross v. Kansas City Power & Light Co., 293 F.3d 1041, 1050 (8th Cir.2002); see also Faragher, 524 U.S. at 806-07, 118 S.Ct. 2275. Here, the Ku Klux Klan letter and the vandalism were indisputably carefully investigated, albeit without success, by the agency. And the Halloween costume incident was not even known to the agency, largely because plaintiff chose not to report it, which is a further reason this incident does not provide a basis for finding a hostile work environment. See Faragher, 524 U.S. at 806-07, 118 S.Ct. 2275; Woodland v. Joseph T. Ryerson & Son. Inc., 302 F.3d 839, 844 (8th Cir.2002) (noting that plaintiff failed to report incidents he alleged were part of a hostile work environment).
When the facts of these three incidents are fully taken into account, it is apparent that they cannot, individually or collectively, sustain a hostile work environment claim. The remaining question, then, is whether plaintiff can now support a hostile work environment claim by reference to her allegations of myriad specific discriminatory acts against her. The Court concludes that effort is also to no avail. To begin with, as discussed above, the Court concludes that plaintiff cannot sustain her claims of discrimination as to these alleged events, in large part because they were not adverse employment actions. Hence, they cannot satisfy the requirement that plaintiff show a pervasive, severe and discriminatory hostile work environment.
Moreover, it is not at all clear that mere reference to alleged disparate acts of discrimination against plaintiff can ever be transformed, without more, into a hostile work environment claim. The courts have been reluctant to do so. See, e.g., Gardner v. Tripp County, South Dakota, 66 F.Supp.2d 1094, 1100-01 (D.S.D.1998) (retaliation claims distinct from hostile work environment claim; “if the same set of facts could support both claims, state and federal provisions that provide a separate cause of action for retaliatory acts would be rendered superfluous”); Parker v. State, Dep’t of Public Safety, 11 F.Supp.2d 467, 475 (D.Del.1998) (“... the dangers of allowing standard disparate treatment
